The U.S. Senate took a rare step Tuesday, advancing legislation aimed at forcing President Donald Trump to withdraw American troops from the ongoing conflict in Iran. The vote, 50-47, showed a small but growing number of Republicans breaking with Trump amid a war that has stretched on for more than two months.
Senate Moves to Limit Trump’s War Powers
Since Trump ordered military action in Iran at the end of February, Democrats have repeatedly introduced war powers resolutions requiring congressional approval for U.S. troops or a withdrawal. In the past, Republicans had enough votes to block these measures, but this week’s tally reflects shifting dynamics.
Louisiana Senator Bill Cassidy, recently defeated in a primary election endorsed by Trump, joined Democrats in supporting the resolution for the first time. Senators Rand Paul of Kentucky, Susan Collins of Maine, and Lisa Murkowski of Alaska again voted in favor, while Democrat John Fetterman of Pennsylvania was the lone “no” vote on his side.
Senate Democratic leader Chuck Schumer noted the growing unease within the Republican ranks, saying, “Republicans are starting to crack, and momentum is building to check him. We are not letting up.”
Trump’s Grip on Senate Republicans Appears to Waver
Cassidy’s primary loss, coupled with Trump’s endorsement of a challenger to Republican Senator John Cornyn, underscores concerns that Trump’s influence over the Senate Republican Conference may be slipping.
In a statement, Cassidy emphasized his commitment to upholding the Constitution: “While I support the administration’s efforts to dismantle Iran’s nuclear program, the White House and Pentagon have left Congress in the dark on Operation Epic Fury. Until the administration provides clarity, no congressional authorization or extension can be justified.”
House Expected to Vote on Similar Resolution
The House is set to vote on a similar war powers resolution Wednesday. Democrats are optimistic after a previous resolution narrowly failed in a tied vote. Even if Congress passes legislation compelling Trump to withdraw, it remains uncertain whether the president would comply.
The administration has argued that a ceasefire technically ended “hostilities,” potentially sidestepping the War Powers Resolution of 1973.
Earlier in the week, Trump reportedly ordered preparations for a new strike on Iran, only to call it off to allow Gulf allies more time to negotiate.
Growing Concern Among Republicans
While some Republicans, like Senator Mike Rounds of South Dakota, continue to support Trump’s approach, there is increasing concern about the lack of a long-term strategy. Rounds noted that the War Powers Resolution allows Congress to debate and discuss military action but suggested that many senators feel it is time to hold the administration accountable.
The move follows a similar process earlier in the year with the Venezuela conflict, where a handful of GOP senators forced a vote on withdrawal legislation after a public hearing on U.S. strategy. Senators Todd Young of Indiana and Josh Hawley of Missouri eventually flipped their votes, highlighting the influence of transparency and oversight on military operations.
Political and Economic Implications
The ongoing Iran conflict has also prompted economic concerns, including rising gas and grocery prices, according to Democratic Senator Chris Murphy of Connecticut. Lawmakers from both parties are pushing for more detailed information about U.S. military plans to ensure accountability and a clear strategy.
This latest Senate vote reflects mounting pressure on Trump from Congress, including some within his own party, as the administration faces scrutiny over the conduct, scope, and long-term plan of the Iran conflict.
