The Trump administration told lawmakers this week that the first six days of the war on Iran have cost the United States at least $11.3 billion, according to a source familiar with a closed-door congressional briefing.

The figure, disclosed to senators during a briefing on Tuesday, does not represent the full cost of the conflict but was shared as Congress seeks more information on the war’s financial impact.

Funding Requests and Congressional Scrutiny

Several congressional aides said the White House is expected to request additional funding for the campaign, with estimates ranging as high as $50 billion. The administration has not released a public cost assessment or provided clarity on the expected duration of the war.

President Donald Trump, speaking in Kentucky on Wednesday, declared, “we won” the conflict so far, while emphasizing that U.S. forces will remain engaged “to finish the job.”

Early Campaign Costs

The conflict began on February 28 with coordinated U.S. and Israeli airstrikes, which have since killed roughly 2,000 people, primarily Iranians and Lebanese, and disrupted global energy markets and transportation. Administration officials reported that $5.6 billion in munitions were used in the first two days of strikes alone.

Lawmakers have expressed concern over the depletion of U.S. military stockpiles, which were already under pressure to meet demand. Last week, Trump met with executives from seven defense contractors as the Pentagon worked to replenish supplies.

Democratic members of Congress are pressing for public, sworn testimony from administration officials regarding war strategy, including the projected timeline and post-conflict plans for Iran.
