Photos have emerged on social media allegedly showing the married couple indicted in connection to a protest at the University of Pittsburgh when it hosted The Daily Wire’s Michael Knowles for a debate on transgenderism in April.

Andy Ngo, a journalist known for his reporting on Antifa’s activism and violence, shared to Twitter on Saturday evening photos that he said were of Brian and Krystal DiPippa, Pittsburgh residents who now face charges over a violent clash with law enforcement at the event.

“Update: Photos of Brian & Krystal DiPippa have been found. These two have a long history of far-left extremism & were federally indicted last week over #Antifa explosive attacks on a [Knowles] event in Pittsburgh,” Ngo said.

“The criminal complaint says the suspects are part of an extremist cell that meets at the Big Idea Bookstore in Pittsburgh,” Ngo added. The journalist further explained that “anarchist bookstores” operate as meeting and training spaces for Antifa.

Ngo also encouraged followers to visit his Locals page, where he posted a related FBI agent’s affidavit in support of a search warrant, which included a timeline and insight into how investigators later identified the DiPippas, who were described as wearing masks during the protest. The 34-page affidavit also noted how investigators were informed that Brian DiPippa repeatedly triggered airport security alarms in May with belongings that tested positive for explosive compound RDX, but security “cleared” the alarms and he was allowed to travel.

“Wow. First I’m seeing the criminal complaint and timeline,” Knowles said in a tweet responding to Ngo. “I haven’t spoken much of this because threats and even physical attacks unfortunately come with the territory for conservatives in public life. But this was far more dangerous and coordinated than I previously knew.”

The Department of Justice (DOJ) announced last week that Brian DiPippa, 36, and Krystal DiPippa, 40, had been indicted by a federal grand jury in Pittsburgh on charges of conspiracy and obstruction of law enforcement. Brian DiPippa was additionally charged with using an explosive to commit a federal felony, according to a U.S. Attorney’s Office news release.

“According to the Indictment, on April 18, 2023, the DiPippas participated in a protest at the O’Hara Student Center on the University of Pittsburgh campus, at which time Brian DiPippa ignited and dropped two homemade smoke bomb containers in and around a line of persons waiting to enter the O’Hara Student Center to attend a scheduled event featuring guest speakers,” the DOJ release said.

“The Indictment further alleges that, when Pitt Police officers gathered and formed a barrier to prevent the protesters from entering the rear of the building, Brian DiPippa, concealed by his wife, Krystal DiPippa, ignited and threw a large explosive firework into the group of Pitt officers, causing a loud explosion and injuries to several officers,” the release added.

The charges of conspiracy and obstruction of law enforcement could warrant a maximum sentence of 10 years in prison, a $500,000 fine, or both if the defendants are found guilty. Using an explosive to commit a federal felony carries a mandatory minimum sentence of 10 years in prison and a maximum fine of $250,000.

Knowles, who participated in the debate titled “Should transgenderism be regulated by law?”  with libertarian journalist Brad Polumbo, reacted to the charges with a tweet that said, “Very pleased to see the FBI arrest a couple of the anarchists who set off an explosive at one of my campus events this semester!”

Treasury Secretary Janet Yellen is facing criticism for bowing repeatedly to a Chinese official during a visit to Beijing on Saturday.

Video published by Reuters shows Yellen smiling and while giving a slight bow three times as she shook hands with Chinese Vice Premier He Lifeng, who did not bow during the seconds-long clip.

“Never, ever, ever,” Bradley Blakeman, a top White House aide to President George W. Bush, told The New York Post in response to the exchange. “An American official does not bow. It looks like she’s been summoned to the principal’s office, and that’s exactly the optics the Chinese love.”

The publication also reported Jerome Cohen, an emeritus professor at New York University and expert in Chinese law and government, said, “Bowing is not part of the accepted protocol.”

Others reacted with disgust on social media as the video of Yellen bowing was shared by various accounts, including one for the Republican National Committee.

“I can’t stand this woman,” tweeted defense attorney Marina Melvin. “BTW she’s bowing to him because she genuinely wants to. It’s natural for her. She’s an obsequious commie lover.”

Grabien founder Tom Elliott said, “Her bowing is an embarrassment to every non-communist American.”

“How many times does she think she has to bow?” asked New York Post columnist Miranda Devine, who added a “grimacing face” emoji.

Yellen had an introductory meeting with He to “build on” U.S. President Joe Biden and Chinese leader Xi Jinping’s “guidance to deepen engagement between key senior officials on macroeconomic issues,” said a readout from the Treasury Department.

“The meeting was candid, constructive, and comprehensive,” the readout added. “While raising issues of concern, Secretary Yellen discussed the Administration’s approach to seek healthy economic competition with China, with a level playing field for American workers and businesses. They also exchanged views on global and domestic macroeconomic outlooks.”

The readout continued, “Secretary Yellen also conveyed that even when the United States and China have disagreements, it is vital that the two countries find ways to work together on issues of shared – and global – concern, including debt distress in low-income and emerging economies and climate finance.”

According to The Washington Post, Yellen flubbed He’s name, calling him “Vice Premier Hu,” as they spoke about shoring up ties between their respective nations during a time of rising tensions.
