US Senate Republicans narrowly defeated a war powers resolution seeking to limit President Donald Trump’s military campaign against Iran, backing the administration as the conflict widens and lawmakers confront the political and human costs of a potentially prolonged war.

Senate Republicans voted down an effort on Wednesday to halt President Donald Trump’s war against Iran, demonstrating early support for a conflict that has rapidly spread across the Middle East with no clear US exit strategy.

The legislation, known as a war powers resolution, failed on a 47–53 vote tally. It gave lawmakers an opportunity to demand congressional approval before any further attacks are carried out. The vote forced them to take a stand on a war shaping the fate of US service members, countless other lives and the future of the region.

Underscoring the gravity of the moment, Democratic senators filled the Senate chamber and sat at their desks as the voting got under way. Typically, senators step into the chamber to cast their vote, then leave.

“Today every senator – every single one – will pick a side,” Senate Democratic leader Chuck Schumer said before the vote. “Do you stand with the American people who are exhausted with forever wars in the Middle East or stand with Donald Trump and Pete Hegseth as they bumble us headfirst into another war?”

Senator John Barrasso, second in Senate Republican leadership, said during the debate that GOP senators would send a message that Democrats were wrong to force a vote on the war powers resolution.

“Democrats would rather obstruct Donald Trump than obliterate Iran’s national nuclear programme,” he added.

After launching a surprise attack against Iran on Saturday, Trump has scrambled to win support for a conflict that Americans of all political persuasions were already wary of entering. Trump administration officials have been a frequent presence on Capitol Hill this week as they try to reassure lawmakers that they have the situation under control.

Defence Secretary Pete Hegseth said on Wednesday that the war could extend eight weeks, a longer timeframe than has previously been floated by the Trump administration. He also acknowledged that Iran is still able to carry out missile attacks even as the US tries to control the country’s airspace.

US service members “remain in harm’s way, and we must be clear-eyed that the risk is still high,” General Dan Caine, chairman of the Joint Chiefs of Staff, said at the same press conference.

Six US military members were killed over the weekend in a drone strike in Kuwait.

Republican Senator Joni Ernst of Iowa acknowledged the human costs of the war in her floor speech. One of the soldiers killed on Sunday was from Iowa and a National Guard unit from her state was also attacked in Syria in December, resulting in the deaths of two other soldiers.

“But now is our opportunity to bring an end to the decades of chaos,” said Ernst, who herself served as an officer in the Iowa National Guard for two decades.

“The sooner the better,” she added.

Trump has also not ruled out deploying US ground troops. He has said he is hoping to end the bombing campaign within a few weeks, but his goals for the war have shifted from regime change to stopping Iran from developing nuclear capabilities to crippling its navy and missile programmes.

The votes in Congress this week represented potentially consequential markers of just where lawmakers stand on the war as they look ahead to midterm elections and the consequences of the conflict.

“Nobody gets to hide and give the president an easy pass or an end-run around the Constitution,” said Senator Tim Kaine, the Virginia Democrat leading the war powers resolution. “Everybody’s got to declare whether they’re for this war or against it.”

Republican leaders have successfully, though narrowly, defeated a series of war powers resolutions pertaining to several other conflicts that Trump has entered or threatened to enter. This one, however, was different.

Unlike Trump’s military campaigns against alleged drug boats or even Venezuelan leader Nicolas Maduro, the attack on Iran represents an open-ended conflict that is already ricocheting across the region. For Republicans who are used to operating in a political party dominated by Trump and his promises of keeping the US out of foreign entanglements, the moment represented a degree of whiplash.

“War is ugly, it always has been ugly, but we’re taking out a regime that has been trying to attack us for quite some time,” said Senator Markwayne Mullin, an Oklahoma Republican.

Meanwhile, Senator Lindsey Graham, a South Carolina Republican who has long pushed Trump to engage overseas, argued that the widening conflict represented an opportunity for Arab and European countries to join in the fight against Iran and the militant groups it supports.

“I don’t mind people being on record as to whether or not they think this is a good idea,” he told reporters, but also argued that too much power over the military was ceded to Congress in the War Powers Act, which mandates that presidents must withdraw troops from a conflict within 90 days if there is no congressional authorisation.

On the other side of the Capitol, an intense debate over the war unfolded before a vote on Thursday. The House first debated a resolution presented by GOP leadership affirming that Iran is the world’s largest state sponsor of terrorism.

Representative Brian Mast, the GOP chairman of the House Foreign Affairs Committee, publicly thanked Trump for taking action against Iran, saying the president is using his own constitutional authority to defend the US against the “imminent threat” of Iran.

Mast, an Army veteran who worked as a bomb disposal expert in Afghanistan, said the Democratic resolution was effectively asking “that the president do nothing”.

Representative Gregory Meeks, the top Democrat on the Foreign Affairs panel, said before the debate that the hardest votes he has taken in Congress have been to decide whether to send US troops to war. “Our young men and women’s lives are on the line,” he said, his voice showing emotion as he emerged from a closed-door briefing late on Tuesday with Trump officials.

At a news conference on Wednesday, several Democratic members who are also veterans of the Iraq and Afghanistan wars spoke about the heavy costs of those conflicts.

One of them was Representative Jason Crow, Democrat of Colorado. “I learned when I was fighting in Iraq and Afghanistan, that when elites in Washington bang the war drums, pound their chest, talk about the costs of war and act tough, they’re not talking about them doing it, they’re not talking about their kids,” Crow said. “They’re talking about working-class kids like us.”
