A look at Japan’s evolving intelligence efforts

Once upon a time — from the 1600s through the 1800s — Japan had a spy corps so famous we know their name today: the ninjas, intelligence agents serving the ruling Tokugawa family.

Over the last 75 years, however, as international spying and espionage has proliferated, Japan has mostly been on the sidelines of this global game. Defeat in World War II, and demilitarization afterward, meant that Japanese intelligence services were virtually nonexistent for decades.

Japan’s interest in spycraft has returned, however. In addition to a notable military expansion — as of last year, the country has aircraft carriers again — Japan is also ramping up its formal intelligence apparatus, as a response to what the country’s chief cabinet secretary has called “the drastically changing security environment” around it.

“Intelligence is a critical element of any national security strategy,” says MIT political scientist Richard Samuels, a leading expert on Japanese politics and foreign policy. “It’s just a question of how robust, and openly robust, any country is willing to make it.”

Examining the status of Japan’s intelligence efforts, then, helps us understand Japan’s larger strategic outlook and goals. And now Samuels has written a wide-ranging new history of Japan’s intelligence efforts, right up to the present. The book, “Special Duty: A History of the Japanese Intelligence Community,” is being published this week by Cornell University Press.

“Japan didn’t have a comprehensive intelligence capability, but they’re heading in that direction,” says Samuels, who is the director of the Center for International Studies and the Ford International Professor of Political Science at MIT. As firm as Japan’s taboo on military and intelligence activity once was, he adds, “that constraint is coming undone.”

Ruffians and freelance agents

Aside from the ninjas, who focused on domestic affairs, Japan’s international intelligence efforts have seen a few distinct phases: a patchy early period, a big buildup before World War II, the dismantling of the system under the postwar U.S. occupation, and — especially during the current decade — a restoration of intelligence capabilities.

Famously, Japan was closed off to much of the rest of the world until the late 19th century. It did not formally pursue international intelligence activities until the late 1860s. By the early 1900s, Japanese agents had found some success: They decoded Russian cables in the Russo-Japanese War of 1904-05 and cut off Russian raids during the conflict.

But as Samuels details in the book, during this period Japan heavily relied on a colorful array of spies and agents working on an unofficial basis, an arrangement that gave the country “plausible deniability” in case these operatives were caught.

“There was an interesting reliance upon scoundrels, ruffians, and freelance agents,” Samuels says.

Some of these figures were quite successful. One agent, Uchida Ryohei, founded an espionage group, the Amur River Society (also sometimes called the Black Dragon Society), which opened its own training school, created Japan’s best battlefield maps and conducted all manner of operations meant to limit Russian expansion. In the 1930s, another undercover agent, Doihara Kenji, became so successful at creating pro-Japanese local governments in northern China, that he became known as “Lawrence of Manchuria.”

Meanwhile, Japan’s official intelligence units had a chronic lack of coordination; they divided along military branches and between military and diplomatic bureaucracies. Still, in the decades before World War II, Japan leveraged some existing strengths in the study of foreign cultures — “The Japanese invented area studies before we did,” says Samuels — and used technological advances to make huge strides in information-gathering.

“They had strengths, they had weaknesses, they had official intelligence, they had nonofficial intelligence, but overall that was a period of great growth in their intelligence capability,” Samuels says. “That of course comes to a crashing halt at the end of the war, when the entire military apparatus was taken down. So there was this period immediately after the war where there was no formal intelligence.”

Japan’s subsequent postwar political reorientation toward the U.S. created many advantages for the country but was simultaneously a source of frustration to some. The country became an economic powerhouse while lacking the same covert capabilities as other countries.  

“The Cold War was a period in which many Japanese in the intelligence world resented having to accommodate to American power in the intelligence world, and resented it,” Samuels says. “They had economic intelligence capability. They were very good at doing foreign economic analysis and were all over the world, but they were underperforming on the diplomatic and military fronts.”

The Asian pivot

In “Special Duty,” Samuels suggests three main reasons why any country reforms its intelligence services: Shifts in the strategic environment, technological innovations, and intelligence failures. The first of these seems principally responsible for the current revival of Japan’s intelligence operations.

As Samuels notes, some Japanese officials wanted to change the country’s intelligence structure during the 1980s — to little avail. The end of the Cold War, and the more complicated geopolitcal map that resulted, provided a more compelling rationale for doing so, without producing many tangible results.

Instead, more recent events in Asia have had a much bigger impact in Japan: namely, North Korean missile testing and China’s massive surge in economic and military power. In 2005, Samuels notes, Japan’s GDP was still twice that of China. A decade later, China’s economy was two and a half times as large as Japan’s, and its military budget was twice as big. U.S. power relative to China has also declined. Those developments have altered Japanese security priorities.

“There’s been a Japanese pivot in Asia,” Samuels notes. “That’s really very important.” Moreover, he adds, from the Japanese perspective, “The question about China is obvious. Is its rise going to be disjunctive, or is it going to be stabilizing?”

These regional changes have led Japan to chart a course of greater confidence in foreign policy — reflected in its growing intelligence function. Since 2013 in particular, after Prime Minister Shinzo Abe took office for a second time, Japan has built up its own intelligence function as never before, making operations more unified and better-supported. Japan still coordinates extensively with the U.S. in some areas of intelligence but is also taking intelligence matters into its own hands, in a way not seen for several decades.

As Samuels notes, Japan’s increasing foreign-policy independence is also supported by voters.

“Japanese public opinion has changed,” Samuels says. “They see the issues now, they talk about it now. Used to be, you couldn’t talk about intelligence in polite company. But people talk about it now, and they’re much more willing to go forward.”

“Special Duty” has been praised by other scholars in the field of Japanese security studies and foreign policy. Sheila Smith of the Council on Foreign Relations in Washington calls it a “truly wonderful book” that “offers much needed insight to academics and policymakers alike as they seek to understand the changes in Japan's security choices. ”

By looking at intelligence issues in this way, Samuels has also traced larger contours in Japanese history: first, an opening up to the world, then the alignment with the U.S. in the postwar world, and now a move toward greater capabilities. On the intelligence front, those capabilities include enhanced analysis and streamlined relations across units, heading toward the full spectrum of functions seen in the other major states.  

“It’s been the assumption that the Japanese just don’t do [intelligence activities], except economics,” Samuels reflects. “Well, I hope after people see this book they will understand that’s no longer the case, and hasn’t been for some time.”

Why fear that the slain Botham Jean case witness was targeted makes sense

Friday evening Joshua Brown, a key witness in ex-Dallas police officer Amber Guyger‘s murder conviction was slain outside his apartment complex, about five miles away from where Botham Jean was shot to death a year ago. Now several activists and community leaders are calling it foul play and demanding an investigation.

“I just spoke with Joshua Browns mother. She is devastated. We all are,” civil rights lawyer Lee Merritt tweeted on Saturday night, confirming that Brown, who used to live in the same apartment complex as Guyger and Jean, had been shot several times by an unknown assailant.

While investigators are being cautious and have yet to announce whether they suspect Brown’s death was connected to his participation in Guyger’s murder trial, many thought leaders and elected officials don’t believe it’s merely a coincidence that he was murdered only two days after a jury handed Guyger her sentence.

Perhaps most notable (for several reasons) amongst those voices is controversial civil rights advocate Shaun King, who on Sunday morning informed his followers that poker player and film producer, Bill Perkins, was offering a financial reward to anyone who could shed light on who killed the 28-year-old.

“My friend and brother Bill Perkins is providing $100,000 for the reward to help us find who murdered Joshua Brown. Joshua was executed,” tweeted King. “He was a lead witness in the murder of Botham Jean & was shot & killed right there in the same apartment complex.”

Cori Bush, who is a candidate for Congress in Missouri, retweeted King’s post with the caption, “Joshua should be alive right now.”

“We won’t stop until we find who murdered Joshua and why,” King followed in another tweet. “It was an execution. They didn’t even steal anything from him.”

We’ve seen this before

Objectively speaking we know some people, particularly those not from marginalized groups, will scoff at the knee jerk reaction to call what happened to Brown an execution. Objectively speaking it is perhaps not wise to jump to any conclusions until a thorough investigation of the shooting is done.

But it would be intellectually dishonest not to admit that many of the people suspicious about his death, feel that way due to several other suspicious deaths that have occurred in the recent past following high profile, racially charged cases.

For instance let’s look at Ferguson and the string of activists who have also mysteriously died in the last few years.

DeAndre Joshua was found in his car with two gunshot wounds to the head the night of the Ferguson verdict in 2014. Two years later, Darren Seals was also found dead with two gunshot wounds to the head in his car. In both of those instances, the cars were set on fire, which is often done to destroy evidence.

Then in 2017, Edward Crawford — the activist featured in that iconic Ferguson protest photo showing him catching an active tear gas canister thrown by police and hurling the explosive back at them — was similarly found shot to death in his car.

READ MORE: Disturbing number of Black men connected to Ferguson protests found dead

Maybe I watch too much “Law & Order” but three Ferguson activists who embarrassed local officials on a national stage, being murdered in the exact same way sounds like an M.O.

However, instead of stating the obvious, police instead announced they believe Crawford shot himself in the back seat of his car either in a suicide or perhaps by accident. But murder? Nah.

Suicide was the same outlandish cause of death cited in October 2018, when Ferguson activist Melissa McKinnies found her son Danye Jones in her backyard hanging from a tree.

“Every few months an activist from Ferguson losses their life or loved one,” wrote one supporter, echoing the sentiments of many. Missouri state Sen. Maria Chappelle-Nadal has also tweeted she too believes a murderer is targeting activists in Ferguson on Twitter.

So now what?

Unfortunately, Ferguson has taught many of us that Black people suspiciously dying after stepping up to do their civic duty, isn’t the sort of thing law enforcement seems to pursue with any sort of urgency. Which is why it’s perhaps understandable why Perkins has decided to take it upon himself to give people a financial incentive to speak up and see that justice is done.

“Every murder is sad,” he explained in his own social media message. “The particulars around this specific set of circumstances make it important that everyone learn why this happened irrespective of the outcome. Either way a killer needs to be caught & I wish in every case these resources could be brought to bear for justice.”

But while it’s great that Perkins has stepped up in this way, the truth is we shouldn’t have to have private citizens cutting six figure checks to get the public to do work that taxpayers are already paying the police to do. What exactly does it say about our justice system that rewards like these are even needed?

And also, is anyone looking out for Bunny?

For those who haven’t heard, Ronnie Babbs, the lone eyewitness who filmed the shocking moments surrounding Jean’s death on her cell phone, goes by the name Bunny. Babbs actually recorded Guyger after hearing the fatal shots followed by Jean reportedly asking Guyger, “Why did you shoot me?”

READ MORE: Diversity of jury seen as key factor in officer’s conviction

As a result of her actions she’s received death threats and even been fired from her job at a pharmaceutical company because people began contacting her job to accuse her of being a radical, anti-police, Black extremist.

“I was brave enough to come forward with information that has helped the DA charge a police officer who murdered an innocent Black man in his own home when nobody else would,” Babbs wrote in her appeal for money on GoFundMe.com. “I was hesitant as I knew the consequences could affect me greatly. I put my own life at risk and decided to help.”

So what will officials say if God forbid something else happens to this woman? I can’t even imagine the terror she’s felt in the last few days since Brown’s murder and how the psychological trauma of being pulled into this case has recked havoc on her life.

In the midst of all that, so many people seem more concerned with giving a convicted killer hugs and gifts of forgiveness than protecting the Black people who put their lives on the line under the guise of justice.

If Dallas police doesn’t step up this investigation, I fear that Amber Guyger won’t be the only person with blood on her hands.

New capsule can orally deliver drugs that usually have to be injected

Many drugs, especially those made of proteins, cannot be taken orally because they are broken down in the gastrointestinal tract before they can take effect. One example is insulin, which patients with diabetes have to inject daily or even more frequently.

In hopes of coming up with an alternative to those injections, MIT engineers, working with scientists from Novo Nordisk, have designed a new drug capsule that can carry insulin or other protein drugs and protect them from the harsh environment of the gastrointestinal tract. When the capsule reaches the small intestine, it breaks down to reveal dissolvable microneedles that attach to the intestinal wall and release drug for uptake into the bloodstream.

“We are really pleased with the latest results of the new oral delivery device our lab members have developed with our collaborators, and we look forward to hopefully seeing it help people with diabetes and others in the future,” says Robert Langer, the David H. Koch Institute Professor at MIT and a member of the Koch Institute for Integrative Cancer Research.

In tests in pigs, the researchers showed that this capsule could load a comparable amount of insulin to that of an injection, enabling fast uptake into the bloodstream after the microneedles were released.

Langer and Giovanni Traverso, an assistant professor in MIT’s Department of Mechanical Engineering and a gastroenterologist at Brigham and Women’s Hospital, are the senior authors of the study, which appears today in Nature Medicine. The lead authors of the paper are recent MIT PhD recipient Alex Abramson and former MIT postdoc Ester Caffarel-Salvador.

Microneedle delivery

Langer and Traverso have previously developed several novel strategies for oral delivery of drugs that usually have to be injected. Those efforts include a pill coated with many tiny needles, as well as star-shaped structures that unfold and can remain in the stomach from days to weeks while releasing drugs.

“A lot of this work is motivated by the recognition that both patients and health care providers prefer the oral route of administration over the injectable one,” Traverso says.

Earlier this year, they developed a blueberry-sized capsule containing a small needle made of compressed insulin. Upon reaching the stomach, the needle injects the drug into the stomach lining. In the new study, the researchers set out to develop a capsule that could inject its contents into the wall of the small intestine.

Most drugs are absorbed through the small intestine, Traverso says, in part because of its extremely large surface area --- 250 square meters, or about the size of a tennis court. Also, Traverso noted that pain receptors are lacking in this part of the body, potentially enabling pain-free micro-injections in the small intestine for delivery of drugs like insulin.

To allow their capsule to reach the small intestine and perform these micro-injections, the researchers coated it with a polymer that can survive the acidic environment of the stomach, which has a pH of 1.5 to 3.5. When the capsule reaches the small intestine, the higher pH (around 6) triggers it to break open, and three folded arms inside the capsule spring open.

Each arm contains patches of 1-millimeter-long microneedles that can carry insulin or other drugs. When the arms unfold open, the force of their release allows the tiny microneedles to just penetrate the topmost layer of the small intestine tissue. After insertion, the needles dissolve and release the drug.

“We performed numerous safety tests on animal and human tissue to ensure that the penetration event allowed for drug delivery without causing a full thickness perforation or any other serious adverse events,” Abramson says.

To reduce the risk of blockage in the intestine, the researchers designed the arms so that they would break apart after the microneedle patches are applied.

Insulin demonstration

In tests in pigs, the researchers showed that the 30-millimeter-long capsules could deliver doses of insulin effectively and generate an immediate blood-glucose-lowering response. They also showed that no blockages formed in the intestine and the arms were excreted safely after applying the microneedle patches.

“We designed the arms such that they maintained sufficient strength to deliver the insulin microneedles to the small intestine wall, while still dissolving within several hours to prevent obstruction of the gastrointestinal tract,” Caffarel-Salvador says.

Although the researchers used insulin to demonstrate the new system, they believe it could also be used to deliver other protein drugs such as hormones, enzymes, or antibodies, as well as RNA-based drugs.

“We can deliver insulin, but we see applications for many other therapeutics and possibly vaccines,” Traverso says. “We’re working very closely with our collaborators to identify the next steps and applications where we can have the greatest impact.”

The research was funded by Novo Nordisk and the National Institutes of Health. Other authors of the paper include Vance Soares, Daniel Minahan, Ryan Yu Tian, Xiaoya Lu, David Dellal, Yuan Gao, Soyoung Kim, Jacob Wainer, Joy Collins, Siddartha Tamang, Alison Hayward, Tadayuki Yoshitake, Hsiang-Chieh Lee, James Fujimoto, Johannes Fels, Morten Revsgaard Frederiksen, Ulrik Rahbek, and Niclas Roxhed.

This is the Can’t-Miss Conference for Creatives of Color

Now in its third year, CultureCon has quickly evolved into one of New York City’s most-anticipated events for creative millennials of color. The one-day experiential conference brings together hundreds of black and brown entrepreneurs, tastemakers, artists, and influencers for celebrity fireside chats, informative panels, and sponsor activations. This year, the conference will take place on Oct. 12 in Brooklyn, New York, and include A-list speakers such as Tracee Ellis Ross, Regina King, Keke Palmer, and Sanaa Lathan. In addition to top industry talent, it will be packed with workshop courses on finance, marketing, and collaboration. Plus, attendees will hear from a variety of black professionals and business experts such as John Henry, Angelina Darrisaw, Dia Simms, and Coltrane Curtis.

Imani Ellis

Imani Ellis, founder of The Creative Collective NYC

So, what’s the magic behind putting together an event of this caliber? Her name is Imani Ellis. The millennial corporate communications director founded the organization that produces the annual conference, The Creative Collective NYC (TheCCnyc), back in 2016. The organization was birthed out of her Harlem apartment after she invited a few friends over for tacos to share ideas in a safe space. The gatherings inside her living room expanded into monthly meet-ups with groups of 10 to 50 people and eventually outgrew her apartment. Today, TheCCnyc is a community-driven network that curates dozens of year-round events and partners with mega-brands like Nike, Live Nation, HBO, and SquareSpace.

In an email, Ellis told BLACK ENTERPRISE that CultureCon, the org’s marquee event, “was created to fill a void in the conference space. Instead of approaching one specific aspect of a person (like their career or their side hustle), CultureCon focuses on everything that makes young creatives thrive.”

CultureCon

CultureCon 2018

Buzz about the conference has caught fire. “The first CultureCon kicked off in October 2017 at Samsung 837 in Meatpacking district with only 150 people,” she tells BE. Last year, there were 500 people just on the waiting list. This year, Ellis is expecting 2,000 attendees. She also added a week of programming leading up to the event. “We want attendees to walk away inspired and ready to walk in their purpose,” she says.

For others looking to curate live events of the like, Ellis’ advice is to start small. “I would suggest starting small and perfecting your format,” she says. “Bigger isn’t always better. Sometimes having the best of a very particular product [or] event type will serve you more than trying to mass-produce a just OK brunch mixer or happy hour. Put yourself in the shoes of your guests[s] and see every detail through their eyes. Once you’ve done that, be open to partnerships that are beneficial.”

Colin Powell urges the GOP leaders to ‘get a grip’ amid Trump’s impeachment inquiry

Former Secretary of State Colin Powell has urged his party members to “get a grip on itself” and grab hold of the reins to openly oppose President Donald Trump and get things under control.

GOP split over impeachment pushback as Democrats plow ahead

“Right now, Republican leaders and members of the Congress ― both Senate and the House ― are holding back because they’re terrified of what will happen to any one of them if they speak out,” Powell told CNN’s Fareed Zakaria during an interview at Ohio’s New Albany Community Foundation last week that aired Sunday, Yahoo reports. “Will they lose a primary?”

As the Democrats drive an impeachment inquiry toward a potential vote by the end of the year, Trump’s allies are struggling.

Powell cautioned Republicans to serve for the country’s best interest and put politics aside.

“When they see things that are not right, they need to say something about it because our foreign policy is in shambles right now, in my humble judgment, and I see things happening that are hard to understand,” said Powell, a moderate Republican.

2nd whistleblower may give House Democrats fresh information

By ERIC TUCKER, RICHARD LARDNER and JILL COLVIN Associated Press
WASHINGTON (AP) — House Democrats leading an impeachment inquiry of President Donald Trump’s dealings with Ukraine may have fresh information to work with after a new whistleblower stepped forward with what the person’s lawyer said was firsthand knowledge of key events.

With Congress out for another week and many Republicans reticent to speak out, a text from attorney Mark Zaid that a second individual had emerged and could corroborate the original whistleblower’s complaint gripped Washington and potentially heightened the stakes for Trump.

Zaid, who represents both whistleblowers, told The Associated Press that the new whistleblower works in the intelligence field and has spoken to the intelligence community’s internal watchdog.

The original whistleblower, a CIA officer, filed a formal complaint with the inspector general in August that triggered the impeachment inquiry. The document alleged that Trump had used a July telephone call with Ukraine President Volodymyr Zelenskiy to investigate a political rival, Joe Biden, and his son Hunter, prompting a White House cover-up.

The push came even though there was no evidence of wrongdoing by the former vice president or his son, who served on the board of a Ukrainian gas company. Trump and his supporters deny that he did anything improper, but the White House has struggled to come up with a unified response.

A second whistleblower with direct knowledge could undermine efforts by Trump and his allies to discredit the original complaint. They have called it politically motivated, claimed it was filed improperly and dismissed it as unreliable because it was based on secondhand or thirdhand information.

A rough transcript of Trump’s call with Zelenskiy, released by the White House, has already corroborated the complaint’s central claim that Trump sought to pressure Ukraine on the investigation.

Text messages from State Department officials revealed other details, including that Ukraine was promised a visit with Trump if the government would agree to investigate the 2016 election and a Ukrainian gas company tied to Biden’s son — the outline of a potential quid pro quo.

Rep. Jim Himes, D-Conn., a member of the House Intelligence Committee, said word of a second whistleblower indicates a larger shift inside the government.

“The president’s real problem is that his behavior has finally gotten to a place where people are saying, ‘Enough,'” Himes said.

Democrats have zeroed in on the State Department in the opening phase of their impeachment investigation. The Intelligence, Oversight and Foreign Affairs committees have already interviewed Kurt Volker, a former special envoy to Ukraine who provided the text messages, and least two other witnesses are set for depositions this week: Gordon Sondland, the U.S. ambassador to the European Union, and Marie Yovanovitch, who was abruptly ousted as the U.S. ambassador to Ukraine in May.

Sen. Lindsey Graham, R-S.C., one of Trump’s most vocal backers, provided perhaps the strongest defense of the Republican president. He said there was nothing wrong with Trump’s July conversation with Zelenskiy and said the accusations look like a “political setup.”

As for Trump, rather than visiting his nearby golf course in Sterling, Virginia, for a second day, he stayed at the White House on Sunday, where he tweeted and retweeted, with the Bidens a main target.

“The great Scam is being revealed!” Trump wrote at one point, continuing to paint himself as the victim of a “deep state” and hostile Democrats.

Aside from Trump’s attempt to pressure Zelenskiy, the July call has raised questions about whether Trump held back near $400 million in critical American military aid to Ukraine as leverage for an investigation of Burisma, a Ukrainian gas company.

Hunter Biden served on the board of Burisma at the same time his father was leading the Obama administration’s diplomatic dealings with Ukraine. Though the timing raised concerns among anti-corruption advocates, there has been no evidence of wrongdoing by either Biden.

Joe Biden, a leading candidate for the 2020 Democratic presidential nomination, wrote in The Washington Post that he had a message for Trump and “those who facilitate his abuses of power. … Please know that I’m not going anywhere. You won’t destroy me, and you won’t destroy my family.”

Additional details about the origins of Trump’s July 25 call with Zelenskiy have emerged over the weekend.

Energy Secretary Rick Perry had encouraged Trump to speak with the Ukrainian leader, but on energy and economic issues, according to spokeswoman Shaylyn Hynes. She said Perry’s interest in Ukraine is part of U.S. efforts to boost Western energy ties to Eastern Europe.

Trump, who has repeatedly has described his conversation with Zelenskiy as “perfect,” told House Republicans on Friday night that it was Perry who teed up the July call, according to a person familiar with Trump’s comments who was granted anonymity to discuss them. The person said Trump did not suggest that Perry had anything to do with the pressure to investigate the Bidens.

Himes appeared on CBS’ “Face the Nation” while Graham spoke on Fox News Channel’s “Sunday Morning Futures.”

University of Kansas apologizes for Snoop Dogg’s stripper-pole performance

If you don’t know that Snoop Dogg parties like a rockstar and brings the heat, booty-shaking ladies, some Gin and Juice and sometimes lights one too when he rolls through, now you know.

Snoop Dogg and family mourn baby grandson’s death

At least that’s what the University of Kansas learned after they invited the “Drop It Like It’s Hot” and “Gin and Juice” hit-maker to perform for the “Late Night in the Phog” preseason celebration, but ultimately apologized Friday night for the raunchiness that accompanied his show.

Snoop got on the mic and rocked it, belting out all his jams during his 35-minute performance at the Allen Fieldhouse. But show officials who booked apparently were surprised when concertgoers were treated to ladies dancing on stripper poles, dropping it and doing splits in bootylicious mini shorts. And snoop made it rain when fake money was shot into the crowd.

For some reason the school expected Snoop Dogg to deliver a clean performance.

“We apologize to anyone who was offended by the Snoop Dogg performance at Late Night. We made it clear to the entertainers’ managers that we expected a clean version of the show and took additional steps to communicate to our fans, including moving the artist to the final act of the evening, to ensure that no basketball activities would be missed if anyone did not want to stay for his show,” the said Kansas athletic director Jeff Long in a statement to the Kansas City Star.

“I take full responsibility for not thoroughly vetting all the details of the performance and offer my personal apology to those who were offended. We strive to create a family atmosphere at Kansas and fell short of that this evening,” Long added.

Snoop on the other hand thanked the school on Instagram for allowing him to do what he’s known to do.

“Thank. U for letting me be me. This is America,” he captioned the post.

50 Cent set to produce docuseries about Tekashi69’s rise and fall

50 Cent is launching a docuseries project that will give the low down on some of his industry friends like Snoop Dogg and foes like Tekashi 6ix9ine.

Cardi B’s post-indictment Instagram photo teases new movie ‘Hustlers’

The rapper who is known for his petty trolls of celebrities is reportedly producing “A Moment in Time” and putting Tekashi’s short-lived rap career on blast, chronicling his rise and unceremonious fall from grace, TMZ reports.

Tekashi turned into a federal informant against Nine Trey Blood gang members and other rappers, something some celebs have dogged him out for.

The docuseries will feature 6 to 8 hour-long episodes that will also highlight Snoop Dogg during a difficult time centered around his murder trial, at the height of his career when “Doggystyle” was the highest-selling hip-hop album in the country.

Also featured will be music producer Scott Storch, former NBA star Rafer Alston and 50 Cent.

50 Cent is never one to hold his tongue so we have to see how this docuseries plays out. But from his past transgressions, we’re pretty sure it’ll be just as petty as his checkered past confrontations.

Let’s not forget that 50 once called out his own “Power” co-star Rotimi for owing him $300k.

Tekashi 6ix9ine plans to decline witness protection and resume his rap career after prison

And the G-Unit rapper used his Instagram account as a part-time collections agency, where over the past year, he has put on blast the likes of Bow WowYoung BuckTeairra MariPower executive producer Randall Emmett as well as series co-star RotimiJackie LongBiz Markie, and Adrien Broner.

Surely Tekashi’s episode will be one to watch!

Deandre Somerville said he has never been arrested and yet faced criminal charges after Judge John Kastrenakis sentenced him to 10 days in jail, one year of probation and 150 hours of community service for failing to show up for a schedule court case, The NY Daily News reports.

According to the judge, Somerville “inconvenienced the court” for at least 45 minutes, and that rubbed the judge the wrong way. Somerville explains that he was chosen as a juror earlier this year and the case started on Aug. 21 but he didn’t wake up until 11:30a a.m.—two hours too late to attend, he thought.

Instead, Somerville who works in an after-school programs for the City of West Palm Beach and Recreation Department, went to work for his afternoon shift thinking that it was pointless to try to attend the trial at that point.

“At work, I was looking at my phone thinking, ‘What’s the worst-case scenario that could happen?’” Somerville recalled. “I thought maybe I would get a fine or something like that.”

While at work, Somerville said he received an urgent call from his grandmother alerting him that police were at the door. His grandfather then urged him to get to the court, where he said he was arrested after he explained to the judge about the delay.

“They handcuffed me in courtroom after that,” Somerville said.

Somerville was also ordered to write an apology letter to judge Kastrenakis who then reduced his probation and community service hours.

After outrage following the sentence, the judge however stood his ground defending the time Somerville served implying that it fit his “crime.”

“I came to conclusion it was deserving of punishment,” Kastrenakis told CNN. “Good people make bad mistakes.”

According to CNN, instead of a year of probation, Somerville will now serve just three months, according to court records. His 150 hours of community service were reduced to 30 hours, which includes reporting to the jury office once a week to give a 10-minute talk on the importance of jury duty.

Somerville’s public defender asked the judge to throw out the case, according to WPTV.
Court records show the judge withheld Somerville’s conviction, and the station reported that the judge said he would entertain a motion in the future to drop the charge.

Scientists observe a single quantum vibration under ordinary conditions

When a guitar string is plucked, it vibrates as any vibrating object would, rising and falling like a wave, as the laws of classical physics predict. But under the laws of quantum mechanics, which describe the way physics works at the atomic scale, vibrations should behave not only as waves, but also as particles. The same guitar string, when observed at a quantum level, should vibrate as individual units of energy known as phonons.

Now scientists at MIT and the Swiss Federal Institute of Technology have for the first time created and observed a single phonon in a common material at room temperature.

Until now, single phonons have only been observed at ultracold temperatures and in precisely engineered, microscopic materials that researchers must probe in a vacuum. In contrast, the team has created and observed single phonons in a piece of diamond sitting in open air at room temperature. The results, the researchers write in a paper published today in Physical Review X, “bring quantum behavior closer to our daily life.”

“There is a dichotomy between our daily experience of what a vibration is — a wave — and what quantum mechanics tells us it must be — a particle,” says Vivishek Sudhir, a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research. “Our experiment, because it is conducted at very tangible conditions, breaks this tension between our daily experience and what physics tells us must be the case.”

The technique the team developed can now be used to probe other common materials for quantum vibrations. This may help researchers characterize the atomic processes in solar cells, as well as identify why certain materials are superconducting at high temperatures. From an engineering perspective, the team’s technique can be used to identify common phonon-carrying materials that may make ideal interconnects, or transmission lines, between the quantum computers of the future.

“What our work means is that we now have access to a much wider palette of systems to choose from,” says Sudhir, one of the paper’s lead authors.

Sudhir’s co-authors are Santiago Tarrago Velez, Kilian Seibold, Nils Kipfer, Mitchell Anderson, and Christophe Galland, of the Swiss Federal Institute of Technology.

“Democratizing quantum mechanics”

Phonons, the individual particles of vibration described by quantum mechanics, are also associated with heat. For instance, when a crystal, made from orderly lattices of interconnected atoms, is heated at one end, quantum mechanics predicts that heat travels through the crystal in the form of phonons, or individual vibrations of the bonds between molecules.

Single phonons have been extremely difficult to detect, mainly because of their sensitivity to heat. Phonons are susceptible to any thermal energy that is greater than their own. If phonons are inherently low in energy, then exposure to higher thermal energies could trigger a material’s phonons to excite en masse, making detection of a single photon a needle-in-a-haystack endeavor.

The first efforts to observe single phonons did so with materials specially engineered to harbor very few phonons, at relatively high energies. These researchers then submerged the materials in near-absolute-zero refrigerators Sudhir describes as “brutally, aggressively cold,” to ensure that the surrounding thermal energy was lower than the energy of the phonons in the material.

“If that’s the case, then the [phonon] vibration cannot borrow energy from the thermal environment to excite more than one phonon,” Sudhir explains.

The researchers then shot a pulse of photons (particles of light) into the material, hoping that one photon would interact with a single phonon. When that happens, the photon, in a process known as Raman scattering, should reflect back out at a different energy imparted to it by the interacting phonon. In this way, researchers were able to detect single phonons, though at ultracold temperatures, and in carefully engineered materials.

“What we’ve done here is to ask the question, how do you get rid of this complicated environment you’ve created around this object, and bring this quantum effect to our setting, to see it in more common materials,” Sudhir says. “It’s like democratizing quantum mechanics in some sense.”

One in a million

For the new study, the team looked to diamond as a test subject. In diamond, phonons naturally operate at high frequencies, of tens of terahertz — so high that, at room temperature, the energy of a single phonon is higher than the surrounding thermal energy.

“When this crystal of diamond sits at room temperature, phonon motion does not even exist, because there’s no energy at room temperature to excite anything,” Sudhir says.

Within this vibrationally quiet mix of phonons, the researchers aimed to excite just a single phonon. They sent high-frequency laser pulses, consisting of 100 million photons each, into the diamond — a crystal made up of carbon atoms — on the off chance that one of them would interact and reflect off a phonon. The team would then measure the decreased frequency of the photon involved in the collision — confirmation that it had indeed hit upon a phonon, though this operation wouldn’t be able to discern whether one or more phonons were excited in the process.

To decipher the number of phonons excited, the researchers sent a second laser pulse into the diamond, as the phonon’s energy gradually decayed. For each phonon excited by the first pulse, this second pulse can de-excite it, taking away that energy in the form of a new, higher-energy photon. If only one phonon was initially excited, then one new, higher-frequency photon should be created.

To confirm this, the researchers placed a semitransparent glass through which this new, higher-frequency photon would exit the diamond, along with two detectors on either side of the glass. Photons do not split, so if multiple phonons were excited then de-excited, the resulting photons should pass through the glass and scatter randomly into both detectors. If just one detector “clicks,” indicating the detection of a single photon, the team can be sure that that photon interacted with a single phonon.

“It’s a clever trick we play to make sure we are observing just one phonon,” Sudhir says.

The probability of a photon interacting with a phonon is about one in 10 billion. In their experiments, the researchers blasted the diamond with 80 million pulses per second — what Sudhir describes as a “train of millions of billions of photons” over several hours, in order to detect about 1 million photon-phonon interactions. In the end, they found, with statistical significance, that they were able to create and detect a single quantum of vibration.

“This is sort of an ambitious claim, and we have to be careful the science is rigorously done, with no room for reasonable doubt,” Sudhir says.

When sending in their second laser pulse to verify that single phonons were indeed being created, the researchers delayed this pulse, sending in into the diamond as the excited phonon was beginning to ebb in energy. In this way, they were able to glean the manner in which the phonon itself decayed.

“So, not only are we able to probe the birth of a single phonon, but also we’re able to probe its death,” Sudhir says. “Now we can say, ‘go use this technique to study how long it takes for a single phonon to die out in your material of choice.’ That number is very useful. If the time it takes to die is very long, then that material can support coherent phonons. If that’s the case, you can do interesting things with it, like thermal transport in solar cells, and interconnects between quantum computers.”

Kanye West praises Republican Party for freeing slaves at Utah Sunday Service

Kanye West has created much buzz over the last 9 months for his soulful Sunday Service. He’s turned the gospel worship experience into a pop-up concert that fans have been able to attend for free in cities from Atlanta to Chicago, and most recently, Salt Lake City, Utah

West used the event to not only proclaim the name of Jesus Christ but also praise Donald Trump and the Republican Party.

Churchgoer not here for Kanye Sunday Service: ‘Slaves worshiping’

Not long after taking the stage, West ranted about the backlash he’s received over his pro-Trump comments. He reminded the crowd that it was the Republican Party and President Abraham Lincoln, who, ahem, abolished slavery in the United States, according to Complex.

“Abraham Lincoln was the Whig Party—that’s the Republican Party that freed the slaves. I ain’t never make a decision based only on my color. That’s a form of slavery — mental slavery. I ain’t drink from the white person fountain. … I ain’t playing with them. All these mind controllers, the media, all of these mind controllers. I find that wherever Christ is where I’ve got my mind at. We find that the love of Christ is where I’ve got my mind back,” West said.

West also informed his audience that social media is “designed to make you think slower.”

He then touched on social justice and the state of incarcerated African-American’s in this country, highlighting how the system is broken in the U.S.

The service in Salt Lake City comes a little over a week after West reported he was set to release a new album, Jesus Is King. The album was due out on Sept. 27, according to an Instagram post by his wife, Kim Kardashian.

Meanwhile, West has embarked on tours around the nation, giving fans last weekend in New York a preview his documentary, Jesus Is King, scheduled to debut Oct. 25 in IMAX theaters.

Travis Scott fires back at ‘false’ cheating rumors

Travis Scott broke his silence and took to Instagram Friday to respond to cheating allegations after news broke about his split with Kylie Jenner.

Almost immediately after the split, his name was linked to Rojean Kar, and rumors began to circulate on the internet streets, according to PEOPLE.

REPORTS: Travis Scott and Kylie Jenner SPLIT after 2 years of dating

“It’s really affecting when u see false things said about u once again these false stories about me cheating are just simply not true. Focusing on life, music, and family at this moment is what’s real,” Scott wrote.

Not only did Scott speak up about the allegations but Rojean Kar, who goes by YungSweetRo on Instagram, also shut the rumors down on Thursday via her private Instagram account, according to E! News.

“None of these rumors are true, it’s just the internet creating a false narrative,” she reportedly wrote on her Instagram Story. “Please stop spreading lies & leave him, her & I alone because it’s affecting real lives. Thank you.”

A source told PEOPLE that “any rumors of cheating are totally and completely false.”

PEOPLE also confirmed on Tuesday that the couple decided to take a break from their two year long relationship.

“They are taking some time but not done. They still have some trust issues but their problems have stemmed more from the stress of their lifestyles,” a source told PEOPLE.

The 22-year-old also confirmed the breakup on Thursday saying, “Travis and I are on great terms. Our main focus right now is Stormi. Our friendship and our daughter is priority,” Jenner wrote on Twitter.

She also used this as a moment to debunk any rumors that she was seeing ex-boyfriend Tyga again.

“The internet makes everything 100 times more dramatic than what it really is. There was no ‘2am date with Tyga. You see me drop two of my friends off at a studio that he happened to be at,” she tweeted.

According to PEOPLE’s source while Jenner “is all about family life and really wants a second baby,” while 28-year-old Scott is focused on his music career.

“She still has trust issues with Travis. He hasn’t been giving her the commitment that she needs,” the source explained. “Travis isn’t ready to give her all that she wants.”

Scott also released a song on Thursday “Highest in the Room,” which seems to highlight his struggle with his relationship.

“I’m doing a show, I’ll be back soon/ That ain’t what she wanna hear,” he raps in the song.

Oprah, Beyoncé, more attend Tyler Perry star-studded gala for studio opening

Tyler Perry went from sleeping in his car, creating stage plays and movies, and has now opened his new massive film studio on Saturday.

The debut of the new Tyler Perry studios, now one of the largest in the country,  took place in Atlanta with plenty of entertainment industry moguls, a red carpet, and a gala to commemorate the special moment, according to The Hollywood Reporter.

Oprah Winfrey, Beyoncé, Spike Lee, Cicely Tyson, Samuel L. Jackson, Halle Berry, among others, attended the gala to celebrate the opening of the 330-acre studio that was once a Confederate army base, the report said.

— Tyler Perry officially unveils the first Black owned studio

“I think it’s pivotal in everything that we’ve done, everything that we’re doing still, that we continue to try to motivate and inspire people,” Perry told The Associated Press on Saturday night as he greeted and shook hands with supporters.

Oprah, Perry’s close friend who also owns a studio, celebrated the the opening.

“He didn’t wait for other people to validate or to say you should go this way or that way. He said I’m going to create my own way and as we can see here, become a force for himself. I remember when he was thinking about buying this place and I said ‘You’d be crazy not to take it,”  she told The AP.

Samuel L. Jackson pointed out Perry’s go-getter mentality as the driving force behind his new studio.

“This is more about Tyler the entrepreneur. The visionary. A guy who understands that ownership means that you can do what you want,” Jackson said.

Antonio Brown seeks $40 million from NFL in grievance claim

Antonio Brown may not be tied to an NFL team at the moment, but he still wants his money.

Brown wanted to be released from the Oakland Raiders, and his wish was granted. He was then picked up by the New England Patriots, which also released him, after accusations of sex assault were filed against him.

Patriots release Antonio Brown after another accusation

Now, Brown is looking to gain close to $40 million from the teams in unpaid salaries, fines, and voided guarantees, according to NFL Network Insider. The NFL Player’s Association has filed grievances against both teams on Brown’s behalf, the sports outlet writes.

Leading up to his dismissal from the Raiders, Brown faced disciplinary issues, including a blowout with the team’s general manager that led to about $215,000 in fines.

“He seeking a week of salary from when he requested to be released from Oakland — $860,294. He’s looking for payment of the guarantees for 2019 and 2020 — $29 million — plus his signing bonus of $1 million, which was divided into two workout bonuses,” according to the NFL Network.

The money from the Patriots Brown is requesting includes a $9 million signing bonus, $64,062 from his Week 1 salary, and the remaining $1.025 million of his guaranteed money, the outlet writes. He also signed a breach of contract grievance against the Patriots.

Antonio Brown blasts Patriots, says he’s done with the NFL in Twitter rant

The NFL report notes that recouping the total sum may be an uphill battle. The grievances aren’t Brown’s only legal battles. He also faces a civil lawsuit coming from claims of sexual assault. He was released by the Patriots in September after a second woman accused him of sexual misconduct.

In the first incident, he was accused of rape in a lawsuit by a former trainer. In the second, an artist alleged that he exposed himself when she was hired to paint a mural at his home. Brown denies the accusations.

Amber Guyger: Key witness in murder conviction slain outside home

A key witness in ex-Dallas officer Amber Guyger‘s murder conviction last week was slain Friday night outside his new apartment complex, about five miles away from where his then-neighbor Botham Jean was shot to death, according to various media reports.

Joshua Brown, who used to live in the same apartment complex as Guyger and  Jean, was shot several times by an unknown assailant at his new place of residence, civil rights lawyer Lee Merritt tweeted on Saturday night.

Amber Guyger: Protests erupt over light sentence

The incident occurred just days after Guyger was sentenced to 10 years in prison in the shooting death of killing of Jean, a 26-year-old accountant.

Brown was shot and killed as he exited his car at an apartment complex, which was not the same place where Guyger killed Jean after entering his apartment, The Washington Post reported.

Brown delivered key testimony that likely aided in Guyger’s conviction. He testified that he was returning home from an outing, when he heard two people meeting by surprise, according to The Times. He then heard two gunshots and immediately ran away. He told the court he did not hear commands like “hands.”

“His murder underscores the reality of the black experience in America,” Merritt wrote. “A former athlete turned entrepreneur — Brown lived in constant fear that he could be the next victim of gun violence, either state sanctioned or otherwise.”

Although it has been reported that Brown was the victim, the Dallas Police Department has not confirmed that Brown was the man murdered because the man found had no identification. An emailed statement from the department said officers had responded to reports of a shooting just after 10:30 p.m. at the Atera Apartments at 4606 Cedar Springs Rd.

The Forgiveness Trap: Botham Jean’s family’s response to Amber Guyger triggers debate

According to Merritt, Brown had moved to a new apartment after living at South Side Flats, where Guyger killed Jean in September 2018.

Brown’s body was found lying on the ground in the parking lot of the Atera apartment complex with multiple gunshot wounds. Paramedics took him to Parkland Memorial Hospital, where he later died of the fatal gunshot wounds, according to The Washington Post.

“Several witnesses heard several gunshots and observed a silver four-door sedan leaving the parking lot at a high rate of speed,” police said.

Brown attended the University of South Florida where he played football before returning home to the state of Texas where he began his own business in Dallas.

Oobleck’s weird behavior is now predictable

It’s a phenomenon many preschoolers know well: When you mix cornstarch and water, weird things happen. Swish it gently in a bowl, and the mixture sloshes around like a liquid. Squeeze it, and it starts to feel like paste. Roll it between your hands, and it solidifies into a rubbery ball. Try to hold that ball in the palm of your hand, and it will dribble away as a liquid.

Most of us who have played with this stuff know it as “oobleck,” named after a sticky green goo in Dr. Seuss’ “Bartholomew and the Oobleck.” Scientists, on the other hand, refer to cornstarch and water as a “non-Newtonian fluid” — a material that appears thicker or thinner depending on how it is physically manipulated.

Now MIT engineers have developed a mathematical model that predicts oobleck’s weird behavior. Using their model, the researchers accurately simulated how oobleck turns from a liquid to a solid and back again, under various conditions.

Aside from predicting what the stuff might do in the hands of toddlers, the new model can be useful in predicting how oobleck and other solutions of ultrafine particles might behave for military and industrial applications. Could an oobleck-like substance fill highway potholes and temporarily harden as a car drives over it? Or perhaps the slurry could pad the lining of bulletproof vests, morphing briefly into an added shield against sudden impacts. With the team’s new oobleck model, designers and engineers can start to explore such possibilities.

“It’s a simple material to make — you go to the grocery store, buy cornstarch, then turn on your faucet,” says Ken Kamrin, associate professor of mechanical engineering at MIT. “But it turns out the rules that govern how this material flows are very nuanced.”

Kamrin, along with graduate student Aaron Baumgarten, have published their results today in the Proceedings of the National Academy of Sciences.

A clumpy model

Kamrin’s primary work focuses on characterizing the flow of granular material such as sand. Over the years, he’s developed a mathematical model that accurately predicts the flow of dry grains under a number of different conditions and environments. When Baumgarten joined the group, the researchers started work on a model to describe how saturated wet sand moves. It was around this time that Kamrin and Baumgarten saw a scientific talk on oobleck.

“We’d seen this talk, and we had a lengthy debate over what is oobleck, and how is it different from wet sand,” Kamrin says. “After some vigorous back and forth with Aaron, he decided to see if we could turn this wet sand model into one for oobleck.”

Granular material in oobleck is much finer than sand: A single particle of cornstarch is about 1 to 10 microns wide and about one-hundredth the size of a grain of sand. Kamrin says particles at such a small scale experience effects that larger particles such as sand do not. For instance, because cornstarch particles are so small, they can be influenced by temperature, and by electric charges that build up between particles, causing them to slightly repel against each other.

“As long as you squish slowly, the grains will repel, keeping a layer of fluid between them, and just slide past each other, like a fluid,” Kamrin says. “But if you do anything too fast, you’ll overcome that little repulsion, the particles will touch, there will be friction, and it’ll act as a solid.”

This repulsion happening at the small scale brings out a key difference between large and ultrafine grain mixtures at the lab scale: The viscosity, or consistency of wet sand at a given packing density remains the same, whether you stir it gently or slam a fist into it. In contrast, oobleck has a low, liquid-like viscosity when slowly stirred. But if its surface is punched, a rapidly growing zone of the slurry adjacent to the contact point becomes more viscous, causing oobleck’s surface to bounce back and resist the impact, like a solid trampoline.

They found that stress was the main factor in determining whether a material was more or less viscous. For instance, the faster and more forcefully oobleck is disturbed, the “clumpier” it is — that is, the more the underlying particles make frictional, as opposed to lubricated, contact. If it is slowly and gently deformed, oobleck is less viscous, with particles that are more evenly distributed and that repel against each other, like a liquid.

The team looked to model the effect of repulsion of fine particles, with the idea that perhaps a new “clumpiness variable” could be added to their model of wet sand to make an accurate model of oobleck. In their model, they included mathematical terms to describe how this variable would grow and shrink under a certain stress or force.

“Now we have a robust way of modeling how clumpy any chunk of the material in the body will be as you deform it in an arbitrary way,” Baumgarten says.

Wheels spinning

The researchers incorporated this new variable into their more general model for wet sand, and looked to see whether it would predict oobleck’s behavior. They used their model to simulate previous experiments by others, including a simple setup of oobleck being squeezed and sheared between two plates, and a set of experiments in which a small projectile is shot into a tank of oobleck at different speeds.

In all scenarios, the simulations matched the experimental data and reproduced the motion of the oobleck, replicating the regions where it morphed from liquid to solid, and back again.

To see how their model could predict oobleck’s behavior in more complex conditions, the team simulated a pronged wheel driving at different speeds over a deep bed of the slurry. They found the faster the wheel spun, the more the mixture formed what Baumgarten calls a “solidification front” in the oobleck, that momentarily supports the wheel so that it can roll across without sinking.

Kamrin and Baumgarten say the new model can be used to explore how various ultrafine-particle solutions such as oobleck behave when put to use as, for instance, fillings for potholes, or bulletproof vests. They say the model could also help to identify ways to redirect slurries through systems such as industrial plants.

“With industrial waste products, you could get fine particle suspensions that don’t flow the way you expect, and you have to move them from this vat to that vat, and there may be best practices that people don’t know yet, because there’s no model for it,” Kamrin says. “Maybe now there is.”

This research was supported, in part, by the Army Research Office and the National Science Foundation.

Already being hailed as “television’s first premium Black western,” Boley takes its inspiration from the true story of Boley, Okla., established in 1904 as one of the largest and most prosperous Black towns in the United States. It was in Boley in the 1930s when a group of Black residents took on notorious gangster Pretty Boy Floyd and his gang of outlaws to successfully defend their town.

Booker T. Washington once described Boley as “the finest Black town in the world.”

All of this was threatened on November 23, 1932, when three members of Charles “Pretty Boy” Floyd’s gang attempted to rob the town’s Farmers and Merchants Bank, the first nationally chartered black-owned bank in Oklahoma. In the melee, the bank’s president and two of Pretty Boy Floyd’s gangsters were killed, one by a bank bookkeeper and the other by townspeople who took up arms and shot at the robbers when they tried to flee. All the money was recovered.

The legacy of the town of Boley and its inhabitants form the backdrop of this limited series, which has been a passion project for Langlais and Universal TV President Pearlena Igbokwe for two decades, according to Deadline.

“Boley was one of those mythic places, like Camelot, that I heard fleeting but exciting tales about,” Langlais told Deadline. “They described a place impossible to believe was real…in the middle of Oklahoma…mentioned Nikolai Tesla…and Pretty Boy Floyd…and a shoot-out during a bank robbery…all in the same breath. So when Pearlena called 20 years ago and asked if I was interested in telling this story, I was ready to jump on a train to find this mythic place. However long it took.”

“Rudy Langlais and I have been trying to tell this story for a long time,” Igbokwe added to the Deadline interview. “It is yet another piece of American history that has been overlooked. The showdown in Boley, Oklahoma is incredibly emotional and incredibly cinematic.”

Jacksonville Jaguars owner buys majority stake in Black News Channel

The Black News Channel, a new Tallahassee-based cable news network launching on November 15, is being backed by Pakistani-American billionaire Shahid “Shad” Khan, who owns the Jacksonville Jaguars.

The channel will launch in 33 million U.S. households and will target an African-American audience, according to WJCT News. The network is news gathered, written and reported by Black people for Black people, reported The New York Post.

Khan has not disclosed the amount of his investment, but a source told The New York Post that it exceeded $25 million. Another source referred to the deal as “open-ended,” explaining that “whatever Khan gets involved in, he’s in all the way.”

“My decision to invest was an easy one,” Khan said, according to The New York Post.

In addition to the Jaguars, Khan also owns England’s Fulham FC soccer team. He is also the lead investor, with his son Tony, in the All Elite Wrestling.

The timing is ripe for the channel, according to the channel’s website.

“The number of cable news networks dedicated to serving the nation’s African American communities remains at ZERO! Black News Channel will be the nation’s first channel to fill this significant void,” the site reads.

BNC’s founder is J.C. Watts, Jr., a former congressman from Oklahoma who also played football in the Canadian Football League. The co-founder is Bob Brillante, who is a veteran of Florida television and helped to launch the Sunshine Network, which has since become Fox Sports Sun.  Brillante also launched Florida’s News Channel, a 24-hour regional cable news network which is now defunct.

Khan said he is backing the Black News Channel’s mission to give voices to issues in the Black community – something he is committed to himself.

“This is a chance for me to make an impact on how African Americans report and consume news and related programming, how their voices are amplified and heard, and how all of us can better connect socially, culturally, economically and more,” Khan said in a news release, according to WJCT News. “I am truly proud to be part of such an ambitious but worthy effort.”

Watts said he’s excited to have Khan’s support.

“Obviously, he’s a successful business person, not just in the Jacksonville area with the Jaguars and the things that he has going on there, but I think nationally and internationally. He’s got a brand that we’re excited and thrilled that he chose to join his brand to our efforts,” said Watts, according to WJCT News.

The Black News Channel will initially be available to 23 million satellite TV households and 10 million cable TV households. Watts told WJCT News that more distribution agreements would be forthcoming.
