FBI Director Christopher Wray announced Tuesday that his chief of staff, James Rybicki, is leaving the bureau for a job in the corporate sector.

Wray said Rybicki, who also served as former FBI Director James Comey’s chief of staff, notified him of his plans to jump to a new job last month.

"Jim Rybicki notified me last month that he will be leaving the FBI to accept an opportunity in the corporate sector," Wray said in a statement.

"While this is an exciting move for the whole Rybicki family, Jim will be dearly missed by the FBI family — and by me personally," he continued, praising the staffer for his "many years of dedication to the Bureau and DOJ [Department of Justice]."

Wray also announced that he has tapped former prosecutor Zachary Harmon to serve as his next top staffer.

"Prior to his time in private practice, where Zack and I worked closely together, he served as a federal prosecutor, first on the front lines and later in DOJ's leadership for then-Deputy Attorney General Larry Thompson," Wray said.

Earlier this month, Rybicki was grilled by lawmakers on the House Oversight and Government Reform and Judiciary committees over the way the FBI handled the probe into Hillary Clinton’s use of a private email server as secretary of State.
