US President Joe Biden and US Vice President Kamala Harris arrive for an event in the Rose Garden of the White House to announce Air Force General Charles Q. Brown, Jr. as the new Chairman of the Joint Chiefs of Staff May 25, 2023, in Washington, DC. Brown would become the second Black officer to serve as chairman of the Joint Chiefs of Staff -- after Colin Powell from 1989-1993 -- at a time when the Pentagon is headed by Lloyd Austin, the country's first Black secretary of defense.
