WASHINGTON (CNN) — President Barack Obama will formally nominate former federal prosecutor James Comey as FBI director, a White House official said on Thursday.
The announcement is expected at a White House ceremony on Friday.
If confirmed by the Senate, Comey would replace Robert Mueller, who is leaving in September after leading the bureau for 12 years.
The appointment comes as the Obama administration wrestles with controversy surrounding national security surveillance programs.
Comey previously worked in the Justice Department under President George W. Bush.
