WASHINGTON, May 14 (Reuters) - The U.S. House of Representatives narrowly defeated a Democratic-led resolution aiming to stop the Iran war until hostilities are authorized by Congress, but the effort to rein in President Donald Trump's military campaign failed by the closest possible margin.
The House voted 212 to 212 on the war powers resolution, meaning it failed because it needed a simple majority to pass.
