WASHINGTON—Sen. Tommy Tuberville ended his monthslong hold on nearly all military promotions, in a protest of the Pentagon’s abortion policy, saying he would allow hundreds of officers to advance while still demanding individual votes for about a dozen four-star generals and admirals. 

“I’m not going to hold the promotions of these people any longer,” the Alabama Republican told reporters Tuesday. “We fought hard. We did the right thing for the unborn and for our military, fighting back against executive overreach and an abortion policy.”
