An Army general who oversaw the US withdrawal from Afghanistan was promoted to a four-star officer after a Republican senator dropped a hold on his nomination, according to a Senate aide.

The U.S. Senate on Monday confirmed the promotion of Army Lieutenant General Christopher Donahue, who had been a commander in Afghanistan during the U.S. withdrawal, after it was briefly blocked by a Republican senator.

The Senate voted to approve the promotion of a general who oversaw troops in the U.S. withdrawal from Kabul, Afghanistan, that had been held by Republican Sen. Markwayne Mullin.
