A bipartisan majority in Congress has voted in favor of a war powers resolution to remove U.S. armed forces from hostilities with Iran.

The Senate voted 50 to 48 on Tuesday afternoon, with four Republicans joining Democrats in support. They were Bill Cassidy of Louisiana, Susan Collins of Maine, Rand Paul of Kentucky and Alaska’s Lisa Murkowski.

The measure, which is not legally binding and will not be sent to the White House for a signature, was approved by the House earlier this month.

President Trump criticized the resolution at the time, writing on Truth Social that the House voted “to limit my War Powers, right in the middle of my final negotiations to end the War with the Islamic Republic of Iran. Who would do such an unpatriotic thing. They know where the negotiations stand. The Democrats are fueled by Trump Derangement Syndrome. They would rather have our Country fail than give me another, of many, victories.”

Tuesday’s vote comes at a moment when the U.S. and Iran are engaged in delicate negotiations to permanently end the conflict, the initial terms of which have been broadly criticized by members of both parties.
