President Donald Trump has fired Air Force Gen. Charles Q. Brown as Chairman of the Joint Chiefs of Staff. In a Truth Social post on Friday evening, Trump announced he was nominating Air Force Lt. Gen. Dan Caine to replace Brown. Trump thanked Brown for his service, calling him a fine gentleman and an outstanding leader, wishing him and his family a great future. “General Caine is an accomplished pilot, national security expert, successful entrepreneur, and a ‘warfighter’ with significant interagency and special operations experience,” wrote Trump.
