After a nearly 10-month impasse over Defense Department nominations in the Senate, the chamber advanced the promotions of more than 400 officers on Tuesday, filling leadership roles across the military services.

Sen. Tommy Tuberville lifted his monthslong chokehold on the Senate’s military confirmation process, allowing hundreds of promotions to move forward.

Sen. Tommy Tuberville (R-AL) is backing down on his hundreds of military holds in the Senate, he announced on Tuesday.

Tuberville announced he was dropping his procedural hold on military confirmations on all but those nominated to be four-star generals and admirals.

Tuberville said he will continue to block the promotion of all senior military positions that are four stars or higher.

Alabama Senator Tommy Tuberville has halted the confirmation and promotion process for nearly 400 military nominations, causing a backlog and leaving critical national security positions vacant.
