Hegseth estimates Iran war has cost $37.5 billion as he defends funding request at fiery hearing

Hegseth said the supplemental war funding is an “urgent, necessary” injection of money, and with President Donald Trump's proposed $1.5 trillion defense budget a generational investment in the military.

“Without these funds, we face critical shortfalls,” Hegseth testified.

But Sen. Patty Murray, the top Democrat on the panel, warned of "another forever war.”

“This war is now spiraling out of control again,” Murray said.

President Donald Trump has said repeatedly that “a deal is near, and the war will be over soon,” she said. "But now, he’s asking for $70 billion more — and for us to just trust him it’ll all work out fine.”

Gen. Dan Caine, chairman of the Joint Chiefs of Staff, and Agriculture Secretary Brooke Rollins were also testifying before the panel. The proposed budget package includes $60 billion and $12 billion for other national security needs, along with $10 billion for farm aid and $10 billion for voting law changes.

Before the hearing, the White House issued a statement urging support of the budget resolution, “without modification — immediately.”

War funds make up the bulk of the GOP budget plan

War funding makes up the bulk of the GOP's new budget proposal, one last priority package the Republicans hope to launch before lawmakers recess to campaign for the midterm elections. The package aims to help farmers struggling under Trump's tariffs and to pay for voter law changes, none of it paid for with offsets.

Most Americans continue to disapprove of how Trump is handling Iran, according to an AP-NORC poll. Gas prices have spiked as Iran works to control oil shipments through the Strait of Hormuz, U.S. munitions are running low from the onslaught of American missile strikes and Trump has shifted away from his own campaign promise not to draw the U.S. into prolonged military conflicts.

Nevertheless, Trump has showed no signs of backing off the war, and the Republicans have largely refused to confront his strategy or use Congress' power of the purse and war powers authority to halt the conflict.

“The commander in chief and the whole Department of War are working very hard to bring this to a resolution,” said House Speaker Mike Johnson at his weekly press conference Tuesday.

Hegseth faced questions over the war and his own leadership

Hegseth appeared before the panel facing a torrent of questions about not only the war, but his own leadership of the department.

Sen. Susan Collins, the Republican chair of the committee, opened the hearing saying it's “deeply troubling” that the Pentagon has blocked or denied promotions to various officers, particularly women and minorities.

Democratic Sen. Jeanne Shaheen of New Hampshire questioned why Hegseth is asking for more money when the department has not yet spent about half the $150 billion Republicans provided the Pentagon in last year's big budget bill.

“Why are you asking the American people to absorb the cost of a war they don't support?” asked Shaheen.

When Hegseth started describing the “historic nature” of Trump’s military strategy, she cut him off. Hegseth later explained that the rest of last year’s budget package would be spent by September.

When GOP Sen. Mike Rounds wanted to know if this funding request would be enough to “get the job done,” the general demurred.

“I can’t answer the question on what it will cost, because the enemy has a vote,” Caine said.

Tensions flared during hours long hearing

Republican Sen. John Kennedy of Louisiana was among several senators demanding answers over the situation in the Strait of Hormuz, asking if Iran will impose tolls on what historically has been an open waterway vital to the flow of oil.

Caine said, “That’s a hypothetical question, and I don’t know the answer to that.”

But Kennedy retorted: “Guys, we need straight answers.”

Tensions exploded toward the end of the more than three-hour hearing.

Sen. Kirsten Gillibrand, D-N.Y., told Hegseth flatly that his war claims don't add up.

Has the U.S. obliterated Iran's nuclear capabilities or not? she demanded to know.

“We're staying laser-focused on the objective,” Hegseth responded, “and you're trying to make campaign commercials.”

Sen. Jon Ossoff, D-Ga., probed Hegseth's past assessments of the war, including the secretary's claims of Iran's surrender.

When Democratic Sen. Gary Peters of Michigan said the administration's war strategy has been a complete "failure," Hegseth erupted.

“Shame on you and others who call this a quagmire and a failure,” Hegseth said.

Peters told the secretary: “You, sir, are the failure."

The senator said it’s not the U.S. troops who are failing, but their leaders. “You don't have a strategy," Peters said. “You don't have a long-term plan to actually win this war.”

Hegseth said Democrats have “Trump Derangement Syndrome” and won't give him the money he needs.

Peters said it's not about money, “but a question of leadership.”

This week, the Senate will consider another war powers resolution, having voted nearly a dozen times to try to halt the conflict.

Republicans work to pass budget over Democratic objections

The GOP budget proposal is expected to flow through the reconciliation process, which enables the majority to approve the plan on its own, over the objections of Democrats in the minority.

It's the same lengthy process Republicans used to approve Trump's big tax cuts bill last summer, as well as Homeland Security money earlier this year.

The proposal is headed toward a House vote this week, which would start the process by instructing various committees to begin drafting the legislation. Johnson can afford only a few defectors from his slim majority, and some conservatives want the funding offset with spending reductions elsewhere.

GOP senators have so far panned the House budget plan, but are waiting to see if Johnson can kickstart the process.
