Sen. Chuck Grassley condemned FBI Director Christopher Wray Thursday for refusing to make public an informant file alleging President Biden was involved in a bribery scheme while serving as vice president.

Grassley (R-Iowa) backed House Oversight Committee Chairman James Comer’s refusal to view the document privately, saying it was “not good enough” for the file to be seen by only a handful of politicians given the allegation facing the president.

“They’ve got to produce this document,” the 89-year-old told Fox News. “They’re up against what the Durham report has said about the shortcomings and the political bias of the FBI, and this is just one more example of them not being forthcoming to the public because the public’s business ought to be public, and there’s no reason for a non-classified document to be held in secret.”  

Comer (R-Ky.) said Wednesday that the FBI chief had confirmed the existence of the FD-1023 informant file detailing a June 2020 allegation that Biden engaged in a $5 million bribery scheme with a foreign national during the Obama administration.

Wray had until Tuesday to share the document with lawmakers following a subpoena from Comer, with the FBI director now vulnerable to contempt proceedings for his refusal to make the file available.

Grassley refused to speak about what exactly the document details, but said it does not endanger any sources, refuting the FBI’s previous claim about the file.

The senator also said that it is yet to be determined how incriminating the file actually is against Biden, if at all, and that the real issue was the “unconstitutional” efforts of the FBI director to keep the document hidden.

“Let’s put it this way. There’s accusations in it, but it’s not for me to make a judgment about whether these accusations are accurate or not,” Grassley said of the FD-1023 file. “It’s my job to make sure the FBI is doing their job, and that’s what this is all about, as far as I’m concerned. The public’s business ought to be public.”

Following the Wednesday call between Comer and Wray, the FBI said in a statement: “Director Wray offered to provide the Committee’s Chairman and Ranking Member an opportunity to review information responsive to the subpoena in a secure manner to accommodate the committee, while protecting the confidentiality and safety of sources and important investigative sensitivities.”

It also said, “The FBI remains committed to cooperating with the Committee in good faith.”

The agency did not immediately respond to The Post’s request for comment.

White House National Security Council spokesman John Kirby had denied that the president was involved in the bribery scheme, saying in response to a question from The Post: “The president has spoken to this. And there’s nothing to these claims.”
