After officially announcing his 2024 presidential bid last week, President Joe Biden is now being accused of involvement in a bribery scheme with a foreign national.

Rep. Jamie Raskin (MA-08), who is also the ranking Democrat on the Oversight Committee said Republicans have been "recycling unsubstantiated claims" that Biden accepted bribe money in exchange for favorable policies back when Biden was vice president, according to the Daily Mail.

Raskin claimed that the bribery accusations could have been something that originated from Rudy Giuliani or Russian agents who were making efforts to influence the 2020 election.

"During this same time period, Rudy Giuliani and Russian agents, sanctioned by Trump's Treasury Department, were peddling disinformation aimed at interfering in the 2020 presidential election," Raskin said, according to the Daily Mail.

"Given Chair Comer's commitment to 'dismantle' the FBI, it's no surprise that he would rely on these unverified tips to attack President Biden in one more baseless partisan stunt."

During a White House briefing on Thursday, the New York Post asked National Security Council Spokesman John Kirby if he knew what country was involved with the alleged bribery scandal, or which policy decision was involved.

"I'm gonna have to refer you to the Justice Department on that. I have nothing for you on that today," Kirby replied.

Sen. Grassley and Rep. Comer Demand Answers, Subpoena Issued

Sen. Chuck Grassley (R-IA) and House Oversight Committee Chairman James Comer (KY-01) said Wednesday that a whistleblower has told them the DOJ and FBI have a file that details an alleged criminal scheme between Biden and a foreign national.

"This comes from a credible and unclassified whistleblower disclosures of this possible criminal activity when Biden was vice president," Grassley told Fox News' Sandra Smith on "America Reports," according to Fox News.

A subponea was issued on Wednesday by Comer in an effort to obtain the FBI document.

"We believe the FBI possesses an unclassified internal document that includes very serious and detailed allegations implicating the current President of the United States," Grassley said in a press release on Wednesday.

"What we don’t know is what, if anything, the FBI has done to verify these claims or investigate further. The FBI’s recent history of botching politically charged investigations demands close congressional oversight," Grassley added.

"The information provided by a whistleblower raises concerns that then-Vice President Biden allegedly engaged in a bribery scheme with a foreign national," Comer said in the same press release.

Rep. Comer says Americans 'Need to Know' if Biden 'Sold Out' US to Make Money

"The American people need to know if President Biden sold out the United States of America to make money for himself. Senator Grassley and I will seek the truth to ensure accountability for the American people," Comer promised.

While Grassley believes the FBI document has a great deal of detail about the bribery activity, he feels there are still several pieces of the puzzle missing regarding that activity.

" What we don’t know is what, if anything, the FBI has done to verify these claims or investigate further. The FBI’s recent history of botching politically charged investigations demands close congressional oversight," Grassley told the Daily Mail.

Grassley has expressed concerns in the past regarding his suspicions about political bias interfering with impartial high-level investigations.

He felt this could be especially true in connection to the foreign business arrangements and bank information of the Biden family.

Though FBI Director Christopher Wray has assured that he will not tolerate any retaliation against whistleblowers,  Grassley feels the FBI and Justice Department haven't been especially cooperative regarding voluntarily providing records or answers in response to congressional inquiries involving politically sensitive investigations.

If the claims are found to be true, many Republicans said they would support impeaching Biden, according to the Daily Mail.
