WASHINGTON (AP) — President Donald Trump has abruptly fired Air Force Gen. CQ Brown Jr. as chairman of the Joint Chiefs of Staff. The move Friday sidelines a history-making fighter pilot and respected officer as part of a targeted campaign to rid the military of leaders who support diversity and equity in the ranks. Brown is only the second Black general to serve as chairman. His 16 months in the job had been consumed with the war in Ukraine and the expanded conflict in the Middle East. But Brown’s future was called into question during the Senate Armed Services Committee’s confirmation hearing for Defense Secretary Pete Hegseth.
