WASHINGTON, May 14 : The US 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 majority to pass, despite more Republicans backing the effort.

Three of Trump’s fellow Republicans — Tom Barrett of Michigan, Brian Fitzpatrick of Pennsylvania and Thomas Massie of Kentucky — backed the resolution, and one Democrat — Jared Golden of Maine — opposed it. It was ‌the third House ‌vote this year on an Iran war powers resolution, and ​the ‌first ⁠since ​the conflict ⁠hit a 60-day deadline on May 1 for Trump to come to Congress about the war. Trump declared then that a ceasefire had “terminated” hostilities against Iran.

There also have been seven failed votes in the Senate.

The votes have been getting tighter, with Trump’s fellow Republicans holding just a slim majority in both chambers. The last House war powers resolution failed on April 16 by 213-214, with one member voting “present.”
