(The Hill) — FBI Director Kash Patel was expected to take heat from the right and the left in back-to-back appearances before Congress amid heightened scrutiny of his performance leading one of the nation’s top investigative agencies.

Patel was set to appear before the Senate and House Judiciary committees starting Tuesday, just days after the FBI’s response to the assassination of Charlie Kirk prompted a flood of GOP criticism about how the director handled the case.

The director was also sure to face questions about the scores of firings that have rocked the bureau, the FBI’s role in reviewing the Epstein files and a number of other moves that Democrats argue have politicized the FBI. 

Patel is not shying away from conflict. 

When Sen. Adam Schiff (D-Calif.) posted a video on the social platform X running through past Patel statements he planned to use as fodder for his questions, the director shot back.

“Let’s find out who law enforcement backs… and who supports defunding the police- answer coming tomorrow, but we already know,” Patel responded.

A longtime ally of President Trump who has been a vocal critic of the multiple investigations into the president, Patel was confirmed in February in a strict party-line vote.

But in the wake of the Kirk shooting, more GOP voices have stepped in to air criticism of Patel’s handling of the case.

Chris Rufo, a vocal opponent of diversity equity and inclusion practices, questioned Friday morning whether Patel has the “operational expertise” to lead the bureau.

“He performed terribly in the last few days, and it’s not clear whether he has the operational expertise to investigate, infiltrate, and disrupt the violent movements—of whatever ideology—that threaten the peace in the United States,” Rufo wrote in a post on X.

Steve Bannon then noted those close to the alleged Kirk shooter turned him in, saying the arrest of Tyler Robinson was “not great law enforcement work.”

Complicating matters for Patel was a stumble in which he announced the arrest of a “subject” in the case — only to reverse course less than two hours later to say they had been released.

It’s unusual for the FBI to offer much public comment about ongoing investigations, while the swift release suggested the bureau had not arrested anyone involved in the shooting.

Patel waved away criticism during a Monday morning appearance on “Fox and Friends,” saying his commitment to change at the bureau includes greater transparency.

“I was being transparent with working with the public on our findings as I had them, I stated in that message that we had a subject and that we were going to interview him, and we did, and he was released,” he said.

“Could I have worded it a little better in the heat of the moment, sure, but do I regret putting it out? Absolutely not. I was telling the world what the FBI was doing as we were doing, and I’m continuing to do that. And I challenge anyone out there to find a director that has been more transparent,” Patel added.

Aside from the controversies surrounding the Kirk investigation, a recently filed suit from three recently fired top leaders recently also adds a wealth of details for lawmakers to pick apart.

Patel fired the acting director who helmed the agency before he was confirmed, Brian Driscoll, along with two other high-level agents, in August, prompting a suit alleging that their removal was part of a “campaign of retribution” for a perceived “failure to demonstrate sufficient political loyalty.”

The suit alleges Patel has been ordered to carry out widespread firings by Trump administration leadership. In another instance, Emil Bove — a senior top Justice Department (DOJ) official at the time — relayed that White House aide Stephen Miller demanded the FBI “conduct summary firings.”

“Patel explained that he had to fire the people his superiors told him to fire, because his ability to keep his own job depended on the removal of the agents who worked on cases involving the President,” the suit says, recounting a conversation between the two men just days before the firings.

According to the suit, Patel explained that there was nothing he or Driscoll could do to stop these or any other firings, because “the FBI tried to put the President in jail and he hasn’t forgotten it.” Driscoll indicated his belief that Patel’s reference to his superiors meant the Justice Department and the White House, and Patel did not deny it.

The FBI has lost an astounding number of leaders since Trump’s inauguration, with the administration firing all top career officials responsible for leading various branches, as well as numerous special agents in charge of field offices. That includes Mehtab Syed, a counterterrorism expert who in February was tapped to lead the Salt Lake Field Office. 

Additionally, while the focus on the Epstein files has waned in the wake of the Kirk shooting, Democrats have already teed up questions for Patel on an FBI review of those filed that spurred a memo saying additional release would not be necessary. 

House Judiciary ranking member Jamie Raskin (D-Md.) wrote Patel last week asking for a breakdown of FBI resources reviewing the files as well as when he became aware Trump was referenced in them.

“Obvious questions abound: why were so many agents tasked with reviewing documents that were never released? What specific instructions were they given during the review? What information did these agents uncover that led DOJ and FBI to reverse their promise to release the files, and how are these decisions related to the President?” Raskin wrote.
