The U.S. Senate on Thursday narrowly rejected a war powers resolution that would have required President Donald Trump to end military hostilities with Iran unless Congress explicitly authorized such action. The vote ended in a 49-50 split, with most Republicans backing the president and opposing the resolution. Four Republican senators—Rand Paul of Kentucky, Susan Collins of Maine, Lisa Murkowski of Alaska, and Thom Tillis of North Carolina—joined Democrats in supporting the measure. Pennsylvania Senator John Fetterman was the only Democrat to vote against it. The resolution, which passed the House in July by a vote of 214-208, would have directed the president to withdraw U.S. forces from the conflict with Iran unless Congress passed a declaration of war or specific authorization for military action. As a concurrent resolution, it would not have required the president's approval or been subject to a veto. The Senate has considered similar war powers resolutions 13 times since the conflict began in February, but Republicans have largely avoided challenging the president directly. The war has led to the deaths of 19 U.S. service members and contributed to rising prices for gas, diesel, fertilizer, and food. A recent poll found that only 33% of registered voters believe the war with Iran was worth it, while 62% do not. Additionally, 57% of voters are more likely to support a candidate who opposes the conflict. Democrats have pushed for over a dozen votes to limit the president's war powers since the start of the conflict, with limited success. However, in May, a measure led by Senator Tim Kaine of Virginia passed the Senate with support from four Republicans. In June, the same four Republicans joined Democrats in adopting a House-passed resolution, which served as a symbolic rebuke of the president. Some Republican candidates running for Senate seats in competitive states have recently expressed opposition to the war, calling for an end to hostilities. Senate Majority Leader John Thune, a Republican from South Dakota, acknowledged growing voter frustration over high fuel prices and encouraged candidates to campaign independently, even if they disagree with the president on certain issues. Democrats have remained determined to continue pressuring Senate Republicans, with Senator Ron Wyden of Oregon stating, “We’re going to stay at it until we win.” Kaine added that the party would keep pushing for votes, noting that some Republican candidates are beginning to shift their positions. Not all Republicans support ending the war, with some arguing that U.S. forces should remain in the region. Senator Dan Sullivan of Alaska said he does not support removing troops while they are in contact with adversaries. Meanwhile, Senator Andy Kim of New Jersey criticized the war as “reckless and expensive,” citing a congressional budget office report that estimated the conflict cost nearly $40 billion in its first four months, along with the deaths of 19 U.S. service members and injuries to over 750 others.
