House Republicans narrowly defeated a bill to end the Iran War, defeating it 213 to 214, with one Republican and one Democrat supporting it. The vote indicates that both chambers of Congress have endorsed President Trump's unilateral powers to conduct war with Iran, despite the practical impact of the vote being negligible. The failure reflects the growing influence of President Trump over the Republican party. Democrats had hoped to secure enough Republicans' support for the resolution, but failed to do so. While most of the country opposes the Iran conflict, Republican voters maintain their support for Trump's actions. The resolution seeks to assert Congress's unique authority to declare war, as defined by Article I of the Constitution.
