Andrew Bailey, who held the position of co-deputy director at the FBI, has resigned from the bureau, multiple outlets reported Monday. Bailey had been brought into the co-deputy role relatively recently before ultimately departing the agency.

His resignation represents one of several significant leadership changes at the FBI since Director Kash Patel assumed control of the agency. Patel, a close ally of former and current administration officials, has overseen a substantial reshaping of the bureau's senior ranks since his confirmation.

Bailey's specific reasons for leaving were not immediately made public. The circumstances of his departure — whether voluntary or prompted by pressure from bureau leadership — were not confirmed in the initial reports, though sources familiar with the matter indicated he would be leaving the bureau entirely rather than moving to another role within it.

The FBI's senior leadership structure has undergone considerable flux in the period following Patel's installation as director. Career officials at multiple levels of the organization have either resigned, retired, or been reassigned as the new leadership team has sought to put its stamp on the nation's premier law enforcement agency.
