Biden selects Air Force general to head NSA and Cyber Command.

President Joe Biden is expected to nominate Gen. "CQ" Brown, current Air Force chief of staff, to be the next chairman of the Joint Chiefs of Staff, making him the senior military adviser to the president and White House. If confirmed by the Senate, Brown would be the second Black Joint Chiefs chairman after Army Gen. Colin Powell and the first to hold the position while another Black man, Lloyd Austin, serves as secretary of defense. Brown's experience in the Indo-Pacific region and his personal character make him a good fit for the moment, according to former Air Force Secretary Heather Wilson.
