Senator Tommy Tuberville, a Republican from Alabama, is blocking hundreds of military promotions over a Pentagon abortion policy, causing a potential national security crisis. President Joe Biden and National Security Adviser Jake Sullivan have denounced the move, and Senator Tammy Duckworth has warned it will jeopardize the U.S.' ability to lead the free world. Sullivan has warned that the blockade could soon leave the U.S. without a chairman of the Joint Chiefs of Staff or a chief of Naval Operations.
