Senate Republicans blocked a major attempt to halt Donald Trump’s escalating war against Iran, rejecting a war powers resolution that would have required congressional approval for further U.S. military action. The measure failed in the United States Senate by a 47–53 vote, highlighting deep divisions in Washington over the rapidly expanding Middle East conflict. The legislation aimed to reassert Congress’ constitutional authority over war decisions and limit the president’s ability to launch additional strikes without lawmakers’ approval. The vote came just days after the Trump administration ordered surprise strikes on Iranian targets, triggering a dangerous escalation across the region. As tensions rise, lawmakers from both parties are demanding answers about the scope of the mission, the risks to American forces, and whether the United States has a clear exit strategy.
