Republican Iowa Sen. Chuck Grassley doubled down that he believes Christopher Wray has failed his “fundamental duties” as FBI director in a blistering letter expressing he has “no confidence” in Wray’s continued leadership over the agency. 

“For the good of the country, it’s time for you and your deputy to move on to the next chapter in your lives. I’ve spent my career fighting for transparency, and I’ve always called out those in government who have fought against it,” Grassley wrote in a letter to Wray on Monday morning, referring also to the FBI’s deputy director Paul Abbate. “For the public record, I must do so once again now.”

Grassley went on to say he “must express my vote of no confidence in your continued leadership of the FBI. President-elect Trump has already announced his intention to nominate a candidate to replace you, and the Senate will carefully consider that choice. For my part, I’ve also seen enough, and hope your respective successors will learn from these failures,” Grassley, who sits on the Senate Judiciary Committee, continued. 

The longtime Republican senator’s letter comes as Trump’s pick to lead the FBI, Kash Patel, headed to Capitol Hill on Monday to meet with lawmakers, including Grassley, and rally support for his confirmation. 

WHO IS KASH PATEL? TRUMP’S PICK TO LEAD FBI HAS LONG HISTORY VOWING TO BUST UP ‘DEEP STATE’

Before the Senate could potentially confirm Patel as FBI chief under the second Trump administration, Wray would need to step down or be fired, as he is in the midst of a 10-year appointment that does not end until 2027. 

Grassley’s lengthy letter to Wray, which spans 11 pages, detailed specific examples of Wray’s “failures​​” as FBI director, which Grassley said “shattered my confidence in your leadership and the confidence and hope many others in Congress placed in you.” The Iowa senator previously argued that Wray has “failed” as FBI director in a social media message posted one day after Trump nominated Patel as FBI chief. 

TRUMP NOMINATES KASH PATEL TO SERVE AS FBI DIRECTOR: ‘ADVOCATE FOR TRUTH’

Grassley pointed to the FBI’s “unprecedented raid” of Trump’s Mar-a-Lago home in Florida in August 2022 regarding classified documents as an example of Wray’s failures. The Republican senator noted the raid included about 30 armed agents who were authorized to “​​use lethal force if needed” in order to execute the search warrant. 

The agents “even searched the former First Lady’s clothing drawers,” Grassley continued. 

“This raid occurred despite serious questions about the need for it. President Trump apparently was cooperating with the investigation, notwithstanding liberal press reports. He voluntarily turned over 15 boxes of documents months before the FBI’s drastic escalation,” Grassley continued, adding that former Secretary of State Hillary Clinton never faced such a raid “even though she and her staff mishandled highly classified information while using a non-government server.”

He also hit the FBI for acting as an “accomplice to the Democrats’ false information campaign designed to undermine my investigation of alleged Biden-family corruption.”

“On August 6, 2020, as Senator Ron Johnson and I were finishing our report on the Biden family’s financial connections to foreign governments and questionable foreign nationals, you succumbed to pressure from Democrats in Congress and provided an unnecessary briefing that Democratic leadership requested in an effort to falsely label our investigation as Russian disinformation.” 

FBI HAS LONG BEEN ACCUSED OF POLITICIZATION AHEAD OF DEM CONCERN OVER KASH PATEL NOMINATION

“That briefing consisted of information we already knew and information that wasn’t connected to our Biden investigation. We made clear at the time our concern that the briefing would be subject to a leak that would shed false light on the focus of our investigation. Predictably, on May 1, 2021, the Washington Post did just that, falsely labeling our investigation as Russian disinformation,” he continued. 

He added that the FBI “sat on bribery allegations” against Biden when he served as vice president, as well as Biden’s son, Hunter Biden, and Ukrainian officials. 

“Consistent with that FBI failure, yet another glaring example of FBI’s broken promises under your leadership is its inexcusable failure to investigate bribery allegations against former Vice President Joe Biden, while strictly scrutinizing former President Trump. You’ve repeatedly claimed you would ensure the FBI does justice, ‘free of fear, favor, or partisan influence.’ The FBI under your watch, however, had possession of incriminating information against President Biden for three years until I exposed the existence of the record outlining those allegations, but did nothing to investigate it,” he wrote. 

Grassley argued that under Wray’s leadership, the FBI has also shown an “​​outright disdain for congressional oversight,” including failure to provide lawmakers with information related to the “​FBI’s ongoing mishandling of sexual harassment claims” made by female employees. 

“This request was not pulled out of a hat. It was based on credible whistleblower disclosures alleging hundreds of FBI employees had retired or resigned to avoid accountability for sexual misconduct,” Grassley wrote. 

The FBI also “refused” to provide information to lawmakers regarding the vetting process of Afghan nationals amid the Biden administration’s botched withdrawal from the nation in 2021, Grassley added. The FBI also came under fire from Grassley for “refusing to provide information to Congress on the FBI’s ‘Richmond memo,’” which has become known as the anti-Catholic memo for depicting traditional Catholics as violent extremists. 

TRUMP FBI PICK KASH PATEL SHOULD TAKE THESE CONCRETE STEPS TO RESTORE TRUST: FORMER SPECIAL AGENT

“Your and Deputy Director Abbate’s failure to take control of the FBI has hindered my work and others’ work throughout multiple Congresses on matters that needed timely information, and has prevented the truth on some issues from ever reaching the American people. You’ve also shown a continuing double standard and failure to carry through on promises,” Grassley wrote in his letter.

When asked about Grassley’s letter, the FBI told Fox News Digital that “the FBI has repeatedly demonstrated our commitment to responding to Congressional oversight and being transparent with the American people.”

“Director Wray and Deputy Director Abbate have taken strong actions toward achieving accountability in the areas mentioned in the letter and remain committed to sharing information about the continuously evolving threat environment facing our nation and the extraordinary work of the FBI.”

TRUMP TRANSITION SIGNS AGREEMENT FOR FBI BACKGROUND CHECKS

Trump joined NBC’s “Meet the Press” for an interview that aired Sunday, where the president-elect also slammed Wray and said the “FBI’s respect has gone way down over the last number of years.”

“He invaded my home. I’m suing the country over it. He invaded Mar-a-Lago. I’m very unhappy with the things he’s done. And crime is at an all-time high. Migrants are pouring into the country that are from prisons and from mental institutions, as we’ve discussed. I can’t say I’m thrilled,” Trump said during the interview. 

“I certainly can not be happy with him. Take a look at what’s happened. And then when I was shot in the ear, he said, maybe it was shrapnel. Where’s the shrapnel coming from? Is it coming from heaven? I don’t think so. So we need somebody to – you know, I have a lot of respect for the FBI. But the FBI’s respect has gone way down over the last number of years,” Trump continued. 

Wray has not revealed whether he will voluntarily step down as FBI director, with Trump expected to fire Wray in order to make room for Patel as FBI director.

Patel is a longtime Trump ally and crusader against the “deep state,” who has advocated for the firings of  “corrupt actors” within the FBI, “aggressive” congressional oversight over the agency, complete overhauls to special counsels, and moving the FBI out of Washington, D.C.

Fox News Digital reached out to the White House for comment on Grassley’s letter, but did not immediately receive responses.
