The House Oversight Committee will begin the process of holding FBI director Christopher Wray in contempt of Congress, committee chairman James Comer announced Monday, citing the bureau’s continued refusal to turn over a whistleblower document alleging President Biden’s involvement in a bribery scheme.

Comer said that FBI officials confirmed the credibility of the FBI-generated whistleblower document — which alleges that then-vice president Biden received $5 million as part of a bribery scheme — during a briefing in a secure SCIF on Capitol Hill on Monday.

The bureau agreed to privately brief Comer and ranking Democrat Jamie Raskin after the chairman threatened to hold Wray in contempt for refusing to turn over the document to the committee, but the concession does not appear to have assuaged Comer’s concerns.

“At the briefing, the FBI again refused to hand over the unclassified record to the custody of the House Oversight Committee,” Comer said. “And we will now initiate contempt of Congress hearings this Thursday.”

“Given the severity and complexity of the allegations contained within this record, Congress must investigate further,” Comer continued. “The investigation is not dead. This is only the beginning.”

Comer said that FBI officials confirmed during the briefing that the whistleblower document “has not been disproven and is currently being used in an ongoing investigation by a confidential human source who provided information about the vice president by being involved in a criminal bribery scheme is a trusted, highly credible informant who has been used by the FBI for over ten years and has been paid over 6 figures.”
