Biden nominates history-making fighter pilot for Joint Chiefs chairman.

Sen. Tommy Tuberville's hold on military promotions will also apply to Air Force Gen. C.Q. Brown Jr.'s elevation to chairman of the Joint Chiefs of Staff, according to his spokesperson. Tuberville has been criticized for stalling promotions of over 150 military officials in protest of a recent Department of Defense policy that provides travel expenses and paid time off for service members and their dependents seeking abortions. Biden formally announced Thursday that he has picked Brown to serve as the next chair of the Joint Chiefs of Staff, replacing Army Gen. Mark Milley when his term ends in October.
