FBI Director Robert Mueller appointed Aaron M. Zebley as his new chief of staff Thursday to fill the gap left as the current chief leaves to join the Justice Department’s National Security Division.
Zebley will spearhead priority projects, and manage the day-to-day operations of the director’s office.
Most recently, Zebley served as Mueller’s deputy chief of staff, and before that, his special counsel. He has also worked as a FBI special agent and an Assistant U.S. Attorney in the Eastern District of Virginia from 2005 to 2010.
He will replace current chief of staff John P. Carlin, who was selected to serve as the Principal Deputy Assistant Attorney General in the Justice Department’s National Security Division.
Carlin first joined the department in 1999 through the Attorney General’s Program before transferring to the U.S. Attorney’s Office for the District of Columbia in 2001. He became Assistant U.S. Attorney for the office and also served in the department’s Computer Hacking and Intellectual Property program.
“John’s talents and judgment will be missed here at the bureau, but I look forward to continuing to work with him in his new position,” Mueller said in an email to employees Thursday. “He will continue to work on the national security and law enforcement issues to which he has contributed greatly here at the FBI.”
