Speaker Nancy Pelosi has set a House vote for Thursday on limiting President Donald Trump's ability to take military action against Iran.
The proposal seems certain to draw strong Republican opposition. The proposal comes as Democratic criticism of the U.S. killing of a top Iranian general continues to intensify.
Pelosi says last week's drone strike that killed Gen. Qassem Soleimani was “provocative and disproportionate."
She scheduled the vote after Iran retaliated by firing missiles at two military bases in Iraq housing U.S. troops.
Her announcement also came shortly after administration officials briefed lawmakers on Iran but were criticized by Democrats for being vague.
