The head of the FBI's New York field office who was reported to have resisted Justice Department efforts to scrutinize agents who participated in politically sensitive investigations told coworkers on Monday that he has retired from the bureau after being directed to do so. James Dennehy said in a message to colleagues obtained by The Associated Press that he was told late Friday to put in his retirement papers but was not given a reason. The move comes in a period of upheaval at the bureau as new FBI Director Kash Patel took office last month and as conservative podcast host and Trump loyalist Dan Bongino has been named to serve as deputy director.
