A surprising public confrontation made clear that some of Sen. Tommy Tuberville's colleagues have hit their limit as hundreds of senior military promotions remain stalled. Concerns about Gen. Eric Smith's health emergency and developments in the Middle East have brought the simmering frustration with Tuberville's hold on President Biden's military nominees to the surface. On Wednesday night, several Republicans confronted Tuberville on the Senate floor, urging him to lift his hold for the sake of national security and proposing votes on individual officers whose promotions have been delayed. However, Tuberville rejected their requests, blocking each proposed nominee. This showdown exposed the growing anger among Tuberville's Republican colleagues, but it is unclear if there is enough GOP support for a Democratic plan to change Senate rules temporarily to end the impasse. Sen. Dan Sullivan plans to challenge Tuberville's blockade by seeking swift confirmation of senior officers. Despite concerns about the impact of the backlog on the military amid various crises, Tuberville remains committed to his stance, forcing his colleagues to take a more confrontational approach.
