WASHINGTON (AP) — President Joe Biden is expected to announce Air Force Gen. CQ Brown Jr. to serve as the next chairman of the Joint Chiefs of Staff. Brown is a history-making fighter pilot with years of experience in shaping U.S. defenses to meet China’s rise. If confirmed by the Senate, Brown would replace the current chairman of the Joint Chiefs of Staff, Army Gen. Mark Milley, whose term ends in October. It would be the first time that both the Pentagon’s top military and civilian positions were held by African Americans. Defense Secretary Lloyd Austin is the Pentagon’s current top civilian.
