The U.S. Senate votes to block a Democratic-led effort to restrict President Donald Trump’s ability to continue a war against Iran without congressional authorization. The resolution would halt the conflict unless hostilities are authorized by Congress, reflecting rising concern within Congress about the scope and duration of the war. According to Reuters reporting carried by multiple outlets, the Senate action comes amid signs of unease not only among Democrats but also among some Republicans. In the Senate vote, lawmakers reject the resolution’s advance, with the measure failing to move forward by a margin of 49 to 47. Separately, one outlet reports that the House of Representatives passes a related war powers measure to curb Trump’s Iran war powers, with a vote of 214 to 208 in favor. Together, the reports describe a political split between the House and Senate, with the Senate blocking progress on the resolution while the House supports curbing the president’s war powers absent congressional approval.
