US Senate blocks Democrats’ Iran war resolution but some Republicans break with Trump; question govt over hostilities

The US Senate on May 14, 2026, blocked Democrats’ second attempt to advance a war powers resolution aimed at halting hostilities with Iran, with Republicans unanimously opposing the measure. The 50-49 vote fell short due to Senator John Fetterman of Pennsylvania joining Republicans in opposition, while Senators Lisa Murkowski of Alaska, Susan Collins of Maine, and Rand Paul of Kentucky supported the Democrats. The failed resolution marks growing dissent within the GOP over President Donald Trump’s handling of the conflict, which began in late February. Murkowski, who previously opposed similar measures, became the latest Republican to switch sides, joining Collins and Paul in backing the effort. Earlier this month, Collins reversed her stance, citing concerns about the war’s continuation. Democrats and a small group of Republicans reject the White House’s claim that hostilities ended on the 60-day mark of the conflict, pointing to recent clashes in the Strait of Hormuz and the deployment of at least 50,000 US troops to the region. Defense Secretary Pete Hegseth stated on May 13 that even if the president resumed bombings, he would not seek congressional approval, further fueling opposition. Senator Jeff Merkley of Oregon, the resolution’s sponsor, argued that ongoing military exchanges qualify as a war under international law, despite a reported reduction in intensity. The White House maintains that the ceasefire, announced on March 2, effectively ended hostilities, though Democrats plan to continue pressing for votes to force Republicans to defend their position ahead of midterm elections. A similar resolution narrowly failed in the House last month, with little chance of passage due to Trump’s opposition and potential veto. The conflict remains a divisive issue, with polls indicating broad public opposition to the war.
