The United States Senate has rejected a proposal aimed at limiting President Donald Trump’s authority to conduct military operations in Iran. The measure, which sought to restrict Trump’s ability to launch further military actions without congressional approval, failed by a vote of 47 in favor and 53 against. Lawmakers were largely divided along party lines during the vote.

The proposal called for the withdrawal of U.S. troops from conflicts unless Congress explicitly authorized their involvement. Previous attempts to impose such limits had also failed, and even if this initiative had succeeded, it remained unclear how much it would have altered the course of the conflict. Democrats argued that Trump had bypassed Congress and offered inconsistent justifications for military actions, while most Republicans opposed the measure but indicated they might reconsider if the conflict expanded.

The House of Representatives is scheduled to vote on the same issue tomorrow. Some senators told reporters that if the war continues for several more weeks, they may be more inclined to support future efforts to restrict presidential war powers.
