The U.S. Senate on Wednesday rejected a second attempt to restrict President Donald Trump’s military operations in Iran, voting 48–53 against a war powers resolution introduced by Cory Booker. The outcome largely followed party lines, though there were a few notable cross-party votes. Republican Senator Rand Paul joined Democrats in supporting the measure, while Democratic Senator John Fetterman broke with his party to oppose it.
The resolution aimed to limit what lawmakers described as the administration’s “massive and ongoing” military engagement in Iran. It argued that Congress had been sidelined as tensions escalated and sought to require the president to withdraw U.S. forces from hostilities unless those actions were explicitly authorized by Congress. A similar proposal previously introduced by Tim Kaine also failed to gain sufficient support.
Despite the defeat, Democratic lawmakers are expected to continue pushing forward with additional war powers resolutions in the coming days. Their broader strategy is to compel members of Congress to publicly take a position on U.S. involvement in the conflict. While supporters recognize the difficulty of passing such measures—especially with strong Republican backing for the military effort—they argue that these votes are still significant in shaping the national debate.
At the heart of the dispute is the War Powers Resolution, a law enacted during the final phase of the Vietnam War to limit the president’s ability to commit U.S. forces to armed conflict without congressional approval. However, presidents from both political parties have consistently challenged the law, arguing that it places unconstitutional limits on the executive branch’s authority under Article II of the Constitution. The issue has never been definitively resolved by the Supreme Court of the United States.
Ultimately, the failure of the resolution underscores ongoing tensions between Congress and the White House over war-making powers. While the vote maintains current policy, it also highlights continued concern among some lawmakers about the balance of authority and the need for greater congressional oversight in military decisions.
