Defense Secretary Pete Hegseth testified before a Senate committee Tuesday, confirming the U.S. war against Iran has reached a $37.5 billion cost. As lawmakers confront rising casualties and munitions shortages, the administration faces intense pressure to justify its strategy and clarify the status of a conflict that remains a primary focus of upcoming budget negotiations.
Rising Costs and Budgetary Pressures in the Iran Conflict
During testimony before the Senate Appropriations Committee on July 21, 2026, Defense Secretary Pete Hegseth disclosed that the U.S. military campaign against Iran has now cost $37.5 billion. This figure represents a significant increase from previous estimates; acting Pentagon comptroller Jules Hurst had reported a $29 billion price tag earlier in the same legislative cycle.
The hearing occurred as the White House seeks approval for a $95 billion budget package, which includes $10 billion in aid for famers and $10 billion for voter law changes. Hegseth defended the spending as an urgent, necessary
injection of funds, describing President Trump’s broader $1.5 trillion defense budget request as a generational investment in the military.
Congressional Oversight and Strategic Concerns
Lawmakers on both sides of the aisle utilized the hearing to challenge the administration’s lack of a clear exit strategy. Sen. Patty Murray, the panel’s top Democrat, criticized the ongoing nature of the conflict, warning that the U.S. appears to be entering another forever war.
She noted that despite repeated assurances from the White House that a deal was near, the conflict has continued to escalate.
“This war is now spiraling out of control again,” Murray said. Trump “has told us over 40 times now that a deal is near, and the war will be over soon. But now, he’s asking for $70 billion more — and for us to just trust him it’ll all work out fine.”

Tensions also surfaced regarding the administration’s reliance on Article 2 of the Constitution to bypass formal Congressional approval for military force. Hegseth maintained that the president holds all necessary authorities to conduct the current operations.
Munitions Stockpiles and Troop Casualties
The Pentagon faced sharp questions regarding the impact of the war on U.S. military readiness. While Hegseth denied reports that stockpiles were critically depleted, he acknowledged that the administration is working to increase weapons production.
The human cost of the campaign remains a point of contention. The Pentagon confirmed that 17 service members have died since the conflict began, and nearly 100 have been injured since early July.
Diplomatic Strains and the Search for Mediation
The hearings also highlighted fraying relationships with international allies. Republican senators, including Mitch McConnell, expressed frustration over the administration’s rhetoric toward NATO and other partners. In a heated exchange, Sen. Lindsey Graham questioned Gen. Dan Caine, chairman of the Joint Chiefs of Staff, regarding reports that Pakistan may be allowing Iranian aircraft to utilize its airfields.
“If they actually do have Iranian aircraft parked in Pakistan bases to protect Iranian military assets, that tells me we should be looking, maybe, for somebody else to mediate,” Graham said. “No wonder this damn thing is going nowhere.”

As of July 21, 2026, the status of a ceasefire remains murky. While Hegseth insisted that a ceasefire is in effect,
he struggled to provide specific documentation to lawmakers, describing the situation as a very dynamic
process of ongoing negotiations. Meanwhile, the administration faces the immediate challenge of securing bipartisan support for the supplemental funding package before lawmakers depart for the midterm election campaign trail.
