WASHINGTON The FBI privately briefed lawmakers Monday about an unverified tip the bureau received in 2020 that Joe Biden had been involved in a bribery scheme when he was vice president.

Republicans have said the source of the allegation is highly credible while admitting they dont know whether its true or not.

House Oversight Committee Chair James Comer (R-Ky.) declared after the briefing on Monday that the FBI had not determined the allegation to be untrue, though he didnt say it had found the tip credible, either.

Today, FBI officials confirmed that the unclassified FBI-generated record has not been disproven and is currently being used in an ongoing investigation, Comer told reporters after a briefing in a Capitol basement.

But Rep. Jamie Raskin (D-Md.), the top Democrat on the committee, said he learned from the briefing that the Justice Department under President Donald Trump looked into the tip and found that it wasnt worth a full investigation.

They decided there was no grounds to escalate this up the investigative-prosecutorial chain, Raskin said. If theres a complaint, the complaint is with Attorney General William Barr, the Trump Justice Department and the team that the Trump administration appointed to look into it.

In 2020, Barr said the Justice Department was looking into material that former Trump attorney Rudy Giuliani had gathered from Ukraine in an effort to find dirt on Biden. Barr said at the time that we cant take anything we received from Ukraine at face value. No charges resulted from the Giuliani material, though it may have sparked an investigation into Hunter Biden in addition to one led by federal prosecutors in Delaware.

In a written statement later on Monday, Raskin said that Barrs task force interviewed the source who relayed the tip and that much of the sources uncorroborated material had already been given to the FBI by Giuliani. In August 2020, Attorney General Barr and his hand-picked U.S. Attorney signed off on closing the assessment, having found no evidence to corroborate Mr. Giulianis allegations, Raskin said in the statement.

White House spokesman Ian Sams on Monday called the latest development in the FBI bribery tip saga another fact-free stunt staged by Chairman Comer not to conduct legitimate oversight, but to spread thin innuendo.

Comer has previously said the tip, delivered to the FBI in June 2020, reflected a very credible allegation that Biden had something to do with a $5 million bribe involving a foreign national. The allegation has emerged as a key to Comers quest to tie Biden himself to the influence peddling of his family members, whom Comer has said received millions in sketchy payments from foreign sources.

Comer refused the DOJs initial offer to let lawmakers see the document at FBI headquarters, but then agreed to take a look after the FBI offered to bring it over to the Capitol.

Even though the FBI showed them the document on Monday, Comer said Republicans would still initiate contempt proceedings against FBI Director Christopher Wray because they werent allowed to keep a copy.

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

Asked why he needed his own copy of the form, Comer complained that press accounts of the dispute emphasized that the allegation remains unverified. He stressed that the FBIs source is highly credible and suggested reporters ought to describe the allegations that way.

Remember, the main reason theyre not wanting to make this public is because theyre concerned about the source, Comer said, without explaining why it should be made public anyway.

In a statement, the FBI said providing access to the document in a reading room is a commonsense safeguard used for congressional oversight and in court proceedings in order to protect sources. The escalation to a contempt vote under these circumstances is unwarranted, an FBI spokesperson said.

After the briefing, Raskin stressed that the source himself couldnt vouch for the incriminating tip.

What were talking about here is a confidential human source reporting a conversation with someone else, Raskin said. What were talking about is secondhand hearsay.

The DOJ has maintained that the document reflects unverified claims collected by a line FBI agent, that the form itself lacks context and that disclosing the information could compromise confidential sources and investigations.

Somehow, Comer and Sen. Chuck Grassley (R-Iowa) have previously seen the document, the two said last week. Grassley has repeatedly said he didnt know if the allegations were true, just that he wanted the Justice Department to say whether it had investigated.

We are not interested in whether the allegations against Vice President Biden are accurate or not, Grassley told Fox News last week. Were responsible for making sure the FBI does its job, and thats what we want to know.
