The Senate adopted a resolution on Tuesday, instructing President Trump to either end military operations in Iran or seek congressional authorization to continue. This move marked a significant bipartisan challenge to the ongoing conflict.
The resolution, however, is not legally binding and unlikely to force immediate changes. The 50-to-48 vote included support from four Republicans, showing a notable divergence within a Congress largely aligned with the President on national security.
This decision arose amid Republican concerns over a cease-fire deal made by President Trump with Iran, following nearly five months of hostilities. Some Republicans have questioned the lack of congressional approval for the war and voiced apprehensions over its continuation. They also raised worries about the conflict’s economic impact and its uncertain goals.
This Senate vote was the first time since the 1973 War Powers Resolution that both houses of Congress approved a directive for a president to terminate military engagements. The House passed the measure earlier, overcoming Republican opposition led by party leaders.
Within the Senate, Senator John Fetterman of Pennsylvania was the only Democrat who opposed the resolution. Republicans Rand Paul, Lisa Murkowski, Susan Collins, and Bill Cassidy voted in support. Their votes, alongside the absence of two Republicans critical of such resolutions, including the recently hospitalized Mitch McConnell, allowed the measure to pass.
The War Powers Resolution was initially enacted amid disputes between Congress and President Nixon during the Vietnam War, aiming to restore legislative oversight over military decisions.
