FBI Director Chris Wray appeared before Congress Wednesday when he faced off against Jan. 6 conspiracy theories espoused by Rep. Clay Higgins (R-LA).

Referring to "ghost buses," Higgins sat with a giant poster of a bus terminal behind him and complained that there is a "tremendous amount of evidence" suggesting that undercover FBI agents were sent into D.C. on Jan. 6 to incite insurrectionists.

"You responded. I quote again, ‘I have to be very careful of what I say,’” Higgins said as Wray tried to speak.

“Congressman, as we’ve discussed before, I’m not going to get into where we have or have not used confidential human sources,” Wray replied.

Wray tried to say more, but Higgins wanted to move on.

“You asked for a definitive answer,” Wray said.

“We will move on. It's my time. You said no, you’re not going to answer. That’s cool. We are watching,” Higgins said.

Wray continued to unsuccessfully insist that he would say more: “Mr. Chairman, may I answer the question?”

Higgins quoted an “FBI informant,” saying he was told to march on the Capitol with the Proud Boys militia. “Can you confirm that the FBI had that sort of engagement with your own agents embedded into the crowd on January 6th?”

Wray asked if Higgins was suggesting that the violence on Jan. 6 was part of an orchestrated FBI operation. "The answer is emphatically not."

“You are saying no?” Higgins shouted.

“No, not violence orchestrated by FBI sources or agents,” Wray said.

"I have all this evidence. I’m showing you the tip of this iceberg,” Higgins said, pointing to his blown-up photo of buses.

He didn't present any other evidence.
