The House is expected to vote on legislation to compel President Donald Trump to withdraw from the war with Iran. It's a significant test of lawmakers’ willingness to go along with a conflict the president launched over two months ago without congressional approval. The House vote on Thursday is the latest effort by Democrats to rein in Trump’s military campaigns by using the War Powers Resolution of 1973. Previous votes on similar resolutions have repeatedly failed. But Democrats are hoping that Thursday's vote could be a turning point. The White House argues that the requirements of the War Powers Resolution no longer apply because of the ceasefire with Iran.
