The US Senate yesterday rejected a resolution aimed at curbing President Donald Trump's authority to continue military strikes on Iran, in a narrow congressional show of support for a conflict launched without explicit approval from lawmakers.
The bipartisan measure, introduced by Democrat Tim Kaine and Republican Rand Paul, would have required the withdrawal of US forces from hostilities against Iran unless Congress authorises the campaign.
But with Republicans holding a 53-47 majority in the upper chamber of Congress and largely backing the president's decision to attack Iran alongside Israel, the resolution fell short by exactly that margin.
The vote came five days into a rapidly expanding conflict that has already killed Iran's supreme leader, Ayatollah Ali Khamenei, and several senior figures in Tehran, while US troops have died in an Iranian attack on a US base in Kuwait.
Democrats argue Mr Trump unconstitutionally bypassed Congress when he ordered the air campaign and say the administration has offered shifting justifications for the war.
"Let me say it this way, there was no presentation of any evidence in that room... that suggested that the US faced any imminent threat from Iran," Mr Kaine said after a classified briefing from administration officials.
Republicans have largely rallied behind their leader, though some have signalled their support could wane if the war expands or drags on.
"Roadside bombs coming out of Iran have maimed and killed hundreds, if not thousands, of Americans," Lindsey Graham, one of Mr Trump's top loyalists in the Senate and a longtime advocate of confronting Iran, posted on X.
"They mean it when they say 'death to America.' I'm glad we didn't let it go further. I'm glad we didn't let them build more missiles."
'Knocked out'
For the resolution to pass, Democrats would have needed at least four Republicans to join Mr Paul. One Democrat, Pennsylvania centrist John Fetterman, opposed the resolution.
Even if the measure had cleared the Senate and the House - where a vote on a similar resolution is expected today - Mr Trump would have been able to veto it.
Congress would have needed an almost certainly unattainable two-thirds majority in both chambers to override the president.
Governments around the world have scrambled to evacuate citizens stranded by the war in the Middle East, triggered by the US-Israeli strikes that killed Mr Khamenei and prompted retaliatory missile and drone attacks across the Gulf.
Cities such as Dubai and Riyadh - long seen as insulated from the region's turmoil - have been drawn into the crisis as the conflict spreads across the region.
The debate in Congress over Mr Trump's authority to wage war reflects broader unease on Capitol Hill about the scope and duration of the military campaign.
Administration officials told lawmakers in classified briefings this week that the operation could last weeks and may require additional funding from Congress.
Lawmakers from both parties say the Pentagon could soon seek emergency funds to replenish weapons stockpiles and sustain the operation.
The war powers resolution invoked the 1973 War Powers Act, passed after the Vietnam War, which allows Congress to force votes on military engagements and limits unauthorised conflicts to 60 days.
Democrats had acknowledged the measure faced steep odds but said forcing lawmakers to take a public position on the war was essential.
