Lawmakers express concerns as Trump officials project $50bn more may be needed for Iran war funding.
Published On 12 Mar 2026
Officials from President Donald Trump’s administration have estimated during a congressional briefing this week that the first six days of the war on Iran had cost the United States at least $11.3bn, a source familiar with the matter told the Reuters news agency.
That figure, from a closed-door briefing for senators on Tuesday, did not include the entire cost of the war, but was provided to lawmakers as they have clamoured for more information about the cost.

Several congressional aides have said they expect the White House to soon submit a request to Congress for additional funding for the war. Some officials have said the request could be for $50bn, while others have said that estimate seems low.
The administration has not provided a public assessment of the cost of the conflict or a clear idea of its expected duration. Trump said during a trip to Kentucky on Wednesday that “we won” the war but that the US would stay in the fight to finish the job.
The $11.3bn figure was first reported on Wednesday by The New York Times.
The human cost
The US-Israeli war on Iran has so far killed about 2,000 people, mostly Iranians and Lebanese, as the conflict has spread across the Middle East, with Iranian retaliatory strikes on neighbouring countries hosting US assets, sending energy prices soaring.
The United Nations children’s agency (UNICEF) says the “intensifying conflict” has killed or wounded 1,100 children, creating a “catastrophic” situation for millions of children across the Middle East.
About 800,000 people have already been displaced in Lebanon by relentless Israeli bombardment.
Administration officials also have told lawmakers that $5.6bn of munitions were used during the first two days of strikes.
Members of Congress, who may soon have to approve additional funding for the war, have expressed concern that the conflict will deplete US military stocks at a time when the defence industry was already struggling to keep up with demand.
Democratic lawmakers have demanded public testimony under oath from administration officials about the Republican president’s plans for the war, including how long it might last and what his plans are for Iran once the fighting has stopped.
Trump on Wednesday said the war with Iran may end “soon” because there is “practically nothing left” for the US military to bomb. He did not provide any evidence for that claim.
