Brittany Bernstein of National Review Online reports a major development in congressional oversight of the Biden administration.

House Oversight Committee chairman James Comer issued a subpoena on Wednesday requiring the FBI to turn over an unclassified record that reportedly details allegations of a criminal scheme involving then-Vice President Joe Biden and a foreign national.

The subpoena comes after Republican Senator Chuck Grassley’s office was made aware of the FBI-generated whistleblower form. The FD-1023 form allegedly outlines a scheme involving the exchange of money for policy decisions.

“It has been alleged that the document includes a precise description of how the alleged criminal scheme was employed as well as its purpose,” Grassley and Comer wrote in a letter to FBI director Christopher Wray and attorney general Merrick Garland. “Based on the alleged specificity within the document, it would appear that the DOJ and the FBI have enough information to determine the truth and accuracy of the information contained within it.”

In the letter obtained by National Review, Grassley and Comer write that it “remains unclear what steps, if any, were taken to investigate the matter.”

“The significant public interest in assessing the FBI’s response to this information, as well as growing concern about the DOJ and the FBI’s track record of allowing political bias to infect their decision-making process, necessitate exacting congressional oversight,” the letter adds.

The subpoena calls on Wray to turn over all FD-1023 forms created or modified in June 2020 containing the term “Biden.” 

“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 statement 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.”
