Republican congressional investigators say FBI Director Christopher Wray has confirmed the existence of an FBI form alleging then-Vice President Joe Biden engaged in a “criminal bribery scheme” with a yet-unnamed foreign national.

Rep. James Comer (R-KY), chairman of the House Oversight Committee, and Sen. Chuck Grassley (R-IA) spoke with Wray on Wednesday, and the FBI chief acknowledged that the FD-1023 confidential human source form in the bureau’s possession does indeed exist, but Comer said Wray still faces possible contempt of Congress for his continued refusal to comply with a congressional subpoena demanding the form be handed over to the GOP-led committee.

“Today, FBI Director Wray confirmed the existence of the FD-1023 form alleging then-Vice President Biden engaged in a criminal bribery scheme with a foreign national. However, Director Wray did not commit to producing the documents subpoenaed by the House Oversight Committee,” Comer said in a statement to the Washington Examiner on Wednesday afternoon. “While Director Wray — after a month of refusing to even acknowledge that the form existed — has offered to allow us to see the documents in person at FBI headquarters, we have been clear that anything short of producing these documents to the House Oversight Committee is not in compliance with the subpoena.”

Comer, who is conducting an investigation into Hunter Biden’s overseas business dealings, added that “if the FBI fails to hand over the FD-1023 form as required by the subpoena, the House Oversight Committee will begin contempt of Congress proceedings.”
