On June 13, 2026, a bipartisan majority in Congress voted in favor of a war powers resolution aimed at removing U.S. armed forces from hostilities with Iran. The Senate passed the measure with a vote of 50 to 48, including support from four Republican senators—Bill Cassidy from Louisiana, Susan Collins from Maine, Rand Paul from Kentucky, and Lisa Murkowski from Alaska.
The resolution, however, is not legally binding and will not be sent to the White House for a presidential signature. The House had approved the measure earlier in the month. Senate Minority Leader Chuck Schumer from New York commented on the vote, stating, “Today, Congress stood up to Donald Trump and voted to end his costly, unnecessary, and devastating war with Iran.” He emphasized that Congress, as the only branch with the power to declare war, sends a clear message that U.S. forces must be withdrawn from Iranian hostilities.
After the resolution was passed in the House, President Trump expressed his disapproval via Truth Social. He criticized the vote, suggesting that Democrats would prefer the country to fail rather than allow him another negotiation victory. He described the lawmakers’ action as unpatriotic, noting it occurred during his final negotiations to end the war with Iran.
The Senate’s decision comes at a critical time, as the U.S. and Iran continue delicate negotiations to permanently end their conflict. The initial terms of these discussions have faced criticism from both Democratic and Republican members.
