Before President-elect Donald Trump could say "You're Fired!" - FBI Director Christopher Wray has resigned, and will leave his post at the end of President Joe Biden's term.

Wray's decision comes weeks after Trump nominated Kash Patel as his replacement. Patel, a fierce critic of the FBI, has said he would seek to shrink the agency's power, close its Washington headquarters, fire its top ranks, and prosecute corrupt agents.

While Wray's departure was always in the cards, the move comes two days after Sen. Chuck Grassley (R-IA) wrote an 11-page letter to Wray asking him to step down, accusing him of mismanagement and "failure to take control of the FBI."

"These failures are serious enough and their pattern widespread enough to have shattered my confidence in your leadership and the confidence and hope many others in Congress placed in you," wrote Grassley.

As the Epoch Times notes further, in November 2022, Grassley published FBI documents showing that higher-ranking officials were sometimes penalized less severely than subordinates.

Wray had addressed this disparity, saying in a Bureau-wide email on Dec. 11, 2020, that the agency “has zero tolerance for any form of sexual harassment or sexual misconduct.”

On March 4, 2022, FBI Deputy Director Abbate warned all FBI employees: “Regardless of your rank and title, every one of us has the responsibility to treat everyone with dignity, respect, and professionalism. ... Harassment of any kind will not be tolerated.”

Grassley also mentioned in his letter his inquiry about the vetting of refugees from Afghanistan through the Operation Allies Welcome program. In February 2022, the Department of Justice (DOJ) reported that the Department of Homeland Security had not cross-checked these evacuees against data from the Department of Defense.

As a result, 50 individuals who had been flagged as “potentially significant security concerns” by the National Ground Intelligence Center were allowed into the United States.

Requests to the FBI for further information were ignored, Grassley said.

Wray said “in a classified multi-agency briefing to congressional staff” that he was unsure of the location of other refugees who might pose a threat, Grassley wrote.

“I can’t sit here right now and tell you that we know where all are located at any given time,” Grassley quoted Wray as saying.

He pointed out that one potential terror threat had been foiled when the FBI arrested Nasir Ahmad Tawhedi on Oct. 7 of this year. Tawhedi was allegedly planning a terror attack to disrupt the U.S. election on Nov. 5.

Grassley also accused Wray and the FBI of exercising a double standard by refusing to investigate President Joe Biden’s or former Secretary of State Hillary Clinton’s mishandling of classified information.

President-elect Donald Trump appointed Wray in 2017 after firing the previous director, James Comey. In a recent interview with “Meet the Press,” Trump expressed displeasure over Wray’s performance.

“He invaded my home,” Trump said, referring to the 2022 FBI raid on his Florida residence, Mar-a-Lago.

Trump also cited Wray’s initial claim that his ear was struck by shrapnel instead of an assassin’s bullet, and waning public respect for the FBI as an institution.

“I can’t say I’m thrilled,” he said.

“For the good of the country, it’s time for you and your deputy to move on to the next chapter in your lives,” the letter says.

The agency told The Epoch Times in an emailed statement: “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.”
