INTERNATIONAL – In a significant political development, the United States Senate has voted to halt military action against Iran, delivering one of the strongest congressional rebukes yet to President Donald Trump’s handling of the conflict. According to Al Jazeera and multiple reports cited by Reuters, the Senate approved a war powers resolution by a narrow 50-48 vote, reflecting growing bipartisan concern over a war that has divided lawmakers and much of the American public.
The measure, which had already passed the House of Representatives earlier in June, directs the president to end unauthorized military operations against Iran. The conflict began on February 28, when the United States and Israel launched military strikes against Iranian targets, triggering months of heightened tensions across the Middle East. While most Republicans have backed Trump throughout the crisis, four Republican senators—Susan Collins, Lisa Murkowski, Bill Cassidy, and Rand Paul—joined Democrats in supporting the resolution. Democratic Senator John Fetterman was the lone member of his party to vote against it.
The vote is considered historic because it marks the first time since the passage of the War Powers Act in 1973 that both chambers of Congress have agreed on a measure directing a president to remove U.S. forces from ongoing hostilities. Supporters argue that Congress, not the executive branch alone, holds the constitutional authority to decide when the nation enters war. Senator Tim Kaine, a longtime advocate of congressional oversight on military action, described the outcome as “a big deal,” emphasizing that lawmakers have now clearly stated that the conflict cannot continue without congressional authorization.

Critics of the resolution, however, argue that it could undermine ongoing diplomatic efforts between Washington and Tehran. Senator James Risch warned, “If this passes, the Iranians are going to simply stand up and walk away from negotiations.” The White House also dismissed the measure, insisting it is unconstitutional and lacks legal force. President Trump reportedly criticized the resolution and described it as “meaningless.”
For now, the practical impact of the Senate’s decision remains uncertain. Legal experts continue to debate whether the resolution can compel executive action, and the issue may ultimately be decided in court. Nevertheless, the vote highlights growing unease in Congress over presidential war powers and signals a renewed effort by lawmakers to reassert their role in decisions involving military conflict and national security.
