Federal lawmakers responded with skepticism on Thursday to reports that the Department of Defense has asked the White House to clear a request of more than $200 billion to cover costs tied to the war in Iran. The White House has not yet transmitted a formal request to the House and Senate, and Pentagon and administration officials signaled the total could change.
At a news conference, Secretary of Defense Pete Hegseth said the number was not fixed and defended the need for additional resources. "I think that number could move, obviously. It takes money to kill bad guys," he said. "So were going back to Congress and folks there to ensure that were properly funded for whats been done, for what we may have to do in the future."
Congressional pushback
Members of both parties voiced doubts. Democrats argued that the Pentagon must justify the supplemental request given the substantial defense funding Congress has already approved since the president began his second term in January 2025. Several Republicans likewise expressed surprise at the magnitude of the figure and asked for greater transparency.
Representative Pramila Jayapal of Washington criticized the size of the potential request during floor remarks, asking, "How on Earth are we going to pay for that? It is absolutely ridiculous." Senator Susan Collins, chair of the Appropriations Committee, said she had not been notified about a $200 billion supplemental and called the total "considerably higher than I would have guessed, but I dont know how its broken down." Collins added that she would likely want to hold a public hearing if such a request were sent to Congress.
Cost estimates and public sentiment
Administration briefings to lawmakers have produced preliminary estimates of battlefield spending. Lawmakers who received briefings put the conflicts daily cost in the range of $1 billion to $2 billion, and officials told lawmakers that the first six days of the campaign cost more than $11 billion.
Public opinion appears to be a constraint as well. Polling cited by lawmakers indicates the war lacks broad popular support, with roughly one in four Americans backing the campaign. That political backdrop has further hardened the stance of some Democrats who say lawmakers opposed to the war should not vote to fund it.
Senator Chris Van Hollen of Maryland urged his colleagues to block funding, writing on X that cutting off funds "is the best way to end this war, protect our troops, save civilian lives, and rein in a lawless Administration." He added plainly, "Im a hell no."
Recent appropriations and previous measures
Members noted that the Republican-led Congress has already approved historically large defense budgets since the president started his second term. Last month the president signed the Fiscal 2026 Defense Appropriations Act with about $840 billion in funding. In addition, a major tax cut and spending bill passed last summer contained $156 billion allocated specifically for defense, a measure that passed over strong Democratic objection.
Those actions have become a reference point in arguments over whether another sizable supplemental appropriation is warranted so soon after record outlays.
Operational and political questions
Lawmakers have demanded more detail about the administrations plans and the operational goals that would justify such a large supplemental. The campaign against Iran, which U.S. and Israeli forces launched on February 28, has entered its third week as congressional scrutiny increased. Members cited the human toll - thousands killed and millions disrupted - and noted the global market effects the campaign has caused, saying that energy and stock markets have been roiled.
With the White House yet to send a formal request, the total amount being discussed remains provisional. Lawmakers said they want itemized explanations and public hearings before considering approval, and some signaled they may oppose the measure altogether if sufficient answers are not provided.
Summary of current status: The Pentagon has requested that the White House approve a request exceeding $200 billion to present to Congress to cover costs tied to the Iran war. The president has not yet submitted a formal supplemental request. Lawmakers from both parties have sought more information and in some cases expressed outright opposition to approving such a large sum given recent, substantial defense appropriations.
