WASHINGTON (AP) — FBI Deputy Director Dan Bongino said Wednesday that he will resign from the bureau next month, ending a brief and tumultuous tenure in which he clashed with the Justice Department over the handling of the Jeffrey Epstein files and was forced to reconcile the realities of his law enforcement job with provocative claims he made in his prior role as a popular podcast host.

The departure, which had been expected, would be among the highest-profile resignations of the Trump administration. It comes as FBI leadership has been buffeted by criticism over Director Kash Patel’s use of a government plane for personal purposes and social media posts about active investigations.

Bongino announced his planned departure in a post on X in which he said he was grateful for the “opportunity to serve with purpose.” He did not say precisely when in January he would leave or detail his future plans.

President Donald Trump said earlier Wednesday, in response to a question about Bongino's fate: “Dan did a great job. I think he wants to go back to his show.”

Bongino was always an unconventional pick for the No. 2 job at the FBI, a position that historically has entailed oversight of the bureau’s day-to-day operations and typically has been held by a career agent. Though he had previously worked as a New York City police officer and Secret Service agent, neither he nor Patel had any experience at the FBI before being picked for their jobs.

Nonetheless, Bongino was installed in the role in March by Trump after years as a conservative podcast host, where he used his platform to repeatedly rail against FBI leadership and to encourage conspiracy theories related to the Epstein sex-trafficking case and pipe bombs discovered in Washington on Jan. 6, 2021.

Once in the position, Bongino struggled to placate elements of Trump’s base who expected him to quickly deliver the reform he had claimed was needed at the FBI and to uncover the truths he had said had been hidden by the federal government.

On the Epstein case, for instance, he had previously challenged the official ruling that the wealthy financier had taken his own life in a New York jail soon after his 2019 arrest. But once in the FBI, he said in a Fox News interview: “I’ve seen the whole file. He killed himself.”

Bongino had separately speculated as recently as last year that the pipe bombs placed on the eve of the Jan. 6 Capitol riot were an “inside job” and part of a “massive cover-up.” But after the FBI earlier this month arrested a 30-year-old Virginia man with no evident connection to the federal government, Bongino was pressed about his prior comments.

“I was paid in the past for my opinions,” Bongino said in a Fox News interview. “One day I will be back in that space but that’s not what I’m paid for now. I’m paid to be your deputy director and we base investigations on facts.”
