Sen. Markwayne Mullin, R-Okla., is blocking the promotion of a general who oversaw the U.S. military withdrawal from Afghanistan in 2021. According to The Hill, Lt. General Christopher Donahue was one of nearly 1,000 promotions the Senate Armed Services Committee approved Tuesday, Nov. 19, but when the full chamber voted Thursday, his name was not on the list. 

Lt. Gen. Donahue was nominated by President Biden to be the head of the U.S. Army in Europe. Sources told the outlet Mullin objected to his nomination due to his role in Afghanistan. 

Mullin’s office declined to comment.

“Lt. Gen. Donahue is a graduate of the U.S. Military Academy at West Point and has served his country for more than thirty years,” Pentagon spokesman James Adams told The Hill in a statement. “His appointment comes at an extremely critical time in the European region. We urge the Senate to confirm all of our highly qualified nominees. Holds on our nominees undermine our military readiness.”
