The U.S. Senate on Tuesday approved a war-powers resolution aimed at blocking further military action against Iran — the first time the chamber has passed such a measure, on a vote of 50-48, a stunning turnaround after the 10th attempt. It marked the sharpest rebuke yet of President Trump’s handling of a war now in its fourth month. The resolution, which the House passed earlier this month, does not carry the full force of law and will not go to Trump for his signature, but it stands as the clearest sign that Republican support for the war — and the deal to end it — is cracking.
Four Republicans — Lisa Murkowski of Alaska, Susan Collins of Maine, Rand Paul of Kentucky and Bill Cassidy of Louisiana — joined nearly all Democrats, while Pennsylvania Democrat John Fetterman voted against. The tally tipped partly because two Republicans were absent, including Kentucky’s Mitch McConnell, who was recently hospitalized.
For businesses and households, the vote matters most for what it signals about oil. The war began on Feb. 28, when the United States and Israel struck Iran, and it has kept a risk premium in crude prices and repeatedly threatened traffic through the Strait of Hormuz, the narrow waterway that carries a large share of the world’s oil. Democrats backing the resolution have pointed to the pain at the pump: the nationwide average price of gasoline had risen to $4.53, a figure they used to argue the conflict has cost ordinary Americans.
The timing is delicate. Trump signed a Memorandum of Understanding with Tehran last week that started a 60-day clock for the two sides to reach a broader agreement over ending Iran’s nuclear program. Oil prices have eased on the diplomatic progress after talks in Switzerland, and that easing has pulled energy costs lower. Virginia Democrat Tim Kaine, who led the effort, said the pause in fighting is the moment for Congress to step back and assess “what should the next chapter be.”
Trump has fiercely opposed the measure, and the White House argues the 1973 War Powers Resolution no longer applies because of the ceasefire. Even with Tuesday’s passage, the president can ignore or veto it, and his administration questions the law’s constitutionality. The vote is, in practical terms, symbolic — but symbolism in Washington often shapes what Congress is willing to fund.
And funding is where the business stakes are largest. The Pentagon is seeking about $80 billion from Congress, mostly for the Iran war, to backfill munitions and stockpiles. That sits inside a far larger push: the administration wants roughly $1.5 trillion in defense funding this year, a 50% increase, including $350 billion it hopes to pass through a budget reconciliation package. For contractors that build missiles, interceptors and munitions, the war has meant a surge of new orders; for taxpayers, one of the steepest run-ups in military spending in decades.
The cracks in Republican ranks have widened for weeks. Texas Senator Ted Cruz said the president was “getting very poor advice on Iran,” and several Republicans argue Trump’s legal window to wage war without congressional approval has expired. Under the War Powers Resolution, a president has 60 days to engage in a conflict before Congress must authorize it. Some Republicans framed their votes as following the law rather than opposing Trump.
What happens next is uncertain. The resolution forces no immediate change, and the fragile truce is holding. But the vote raises the political cost of any return to open conflict and complicates the administration’s drive for military funding. For energy markets, the message is mixed: diplomacy is calming oil prices for now, but the Strait of Hormuz remains a pressure point, and any breakdown in the 60-day talks could send crude — and gas-pump prices — climbing again.
