Washington: The US Senate has voted to halt further American military involvement in the Iran conflict, delivering a major political setback to President Donald Trump and highlighting growing concerns in Congress over the use of presidential war powers. The Senate approved the war powers resolution by a narrow 50-48 vote, with four Republican senators joining Democrats in supporting the measure. The resolution, which had already passed the House of Representatives, directs the president to remove US forces from hostilities with Iran unless Congress provides specific authorization for continued military action.

The vote marks a rare moment of bipartisan resistance against a sitting president’s foreign policy decisions. It is also the first time both chambers of Congress have approved a measure using the framework of the War Powers Resolution of 1973 to push a president to end military involvement in a conflict. The decision comes amid increasing debate in Washington over whether the president has exceeded constitutional limits by continuing military operations without direct approval from lawmakers. Supporters of the resolution argued that Congress must have a stronger role in decisions involving war, especially when American troops are involved in overseas conflicts.

The Trump administration has opposed the move, arguing that the resolution could interfere with national security decisions and diplomatic efforts. The White House has also questioned the legal authority of the measure, calling it an attempt to limit the president’s ability to respond to international threats. The Senate vote also revealed cracks within Trump’s Republican support base. While most Republicans backed the president’s position, a small group broke ranks and supported the resolution, reflecting concerns among some lawmakers about the long-term consequences of the Iran conflict.

Although the resolution sends a strong political message, its immediate impact on US military operations remains uncertain. Experts say the measure could lead to further legal and constitutional debates over the balance of power between the White House and Congress when it comes to military action. The development comes as tensions between the United States and Iran continue to attract international attention. Any shift in Washington’s approach could influence diplomatic talks, regional security calculations, and global energy markets. The Senate vote represents one of the biggest challenges to his Iran policy from within the US political system. For Congress, it signals a renewed effort to reclaim its authority over decisions related to war and military engagement.
