Sen. Tommy Tuberville (R-AL) blocked the promotion of an Army general over the role he allegedly played in keeping Defense Secretary Lloyd Austin’s hospitalization under wraps months ago.

Lt. Gen. Ronald P. Clark is Austin’s senior military assistant who is in the running to become the four-star commander of the U.S. Army forces in the Pacific. His promotion is now stalled in the Senate after Tuberville blocked his nomination, according to a report from the Washington Post on Monday.
