Defense Secretary Pete Hegseth returned to Capitol Hill on Wednesday for a classified briefing with House Republicans, one of several visits over the past month as the Trump administration pushes for nearly $88 billion in supplemental funding for the Iran war alongside a massive $1.5 trillion defense budget request. The effort faces an uphill climb as GOP fiscal conservatives demand that any new military spending be offset by cuts elsewhere.
The administration has asked Congress to approve $350 billion in defense funding through a third reconciliation bill, on top of the Pentagon's $1.15 trillion base budget request. This week it added a supplemental request for Operation Epic Fury — the official name for the Iran conflict — totaling $87.6 billion, including $67 billion for the Defense Department and funding for embassy security at U.S. facilities damaged during the war in Bahrain, Dubai, Karachi, Lahore and Riyadh.
What the Right Is Saying
Several prominent Republican fiscal hawks expressed skepticism about the administration's requests during and after Hegseth's briefings. Rep. Chip Roy of Texas, a leader of the House Freedom Caucus, told reporters that support for the Iran supplemental would be contingent on dollar-for-dollar cuts elsewhere in the budget.
"The administration is talking about 'new' defense money for munitions, for back pay, for the war — where's that money coming from?" Roy said. "My view is that has to be dollar-for-dollar."
Rep. Keith Self of Texas echoed that demand, saying he wants to see the full package and its pay-fors before committing support. "I demand pay-fors," Self told reporters, using the term for provisions meant to offset new spending without increasing the deficit.
Rep. Tim Burchett of Tennessee indicated it would be easier to approve additional Pentagon funding if the military passed a clean audit — a goal Hegseth has pledged to achieve by 2028. "Ideally" the defense request would include pay-fors, said Rep. Rich McCormick of Georgia, who sits on the House Armed Services Committee, though he questioned where those offsets could be found.
Rep. Don Bacon of Nebraska said Hegseth made an effective case for the reconciliation defense spending but withheld support until the Pentagon explains how it will replace an Army brigade in Poland that was cut under Hegseth's direction before Trump overruled him and ordered 5,000 troops to the country. "He has yet to put out a plan how he's going to do it," Bacon said of replacing those forces.
On the other side, Republican Study Committee Chair August Pfluger of Texas called the meeting with Hegseth substantive and said conservatives are leading efforts to ensure future generations have necessary resources and weapons systems. "We know that Democrats are going to vote against it," Pfluger told reporters, suggesting Republicans would need near-unity among their conference.
What the Left Is Saying
Democratic lawmakers have not publicly committed to supporting either the reconciliation package or the Iran supplemental, which would require bipartisan backing given it cannot pass through reconciliation's Senate filibuster exemption. Without Democratic support, Republicans face pressure to find offsets for any spending that falls outside reconciliation rules, a constraint that has stalled previous attempts to advance large supplemental packages.
What the Numbers Show
The administration's total defense funding request breaks down as follows: a $1.15 trillion base budget for the Pentagon, $350 billion in defense spending through reconciliation, and an $87.6 billion supplemental primarily for Iran operations. The supplemental includes $67 billion for the Defense Department, $2 billion for the Coast Guard's role in Operation Epic Fury, $40 million for FBI classified programs related to the war, $95.5 million for the Department of Energy's nuclear security missions, and $300 million for embassy security at facilities damaged during the conflict.
The $87.6 billion supplemental is designed to backfill sophisticated munitions stockpiles that have been depleting since before the Iran conflict began. House Budget Committee Chair Jodey Arrington of Texas said Wednesday that reconciliation negotiations are still determining whether the defense top line will be set at $350 billion, $250 billion, or $150 billion.
Arrington emphasized that offsets remain "the centerpiece" of any budget resolution, pointing to anti-fraud provisions as the primary source of savings. "Our commitment is at a minimum that we're not going to increase the deficit," he said, adding that Republicans are targeting cost-neutral legislation with potential deficit reduction.
The Bottom Line
The Trump administration's defense spending agenda faces a narrow path through Congress even with Republican control of both chambers. Fiscal conservatives within the GOP conference hold enough votes to block reconciliation legislation if they remain unified against it, while any supplemental funding requires bipartisan support and therefore cannot advance without Democratic backing or significant changes to offset the costs.
Hegseth has argued in an op-ed for the New York Post that underinvestment in military spending poses the greatest threat to U.S. national security, writing: "If America loses its unquestioned military edge, no amount of fiscal austerity can maintain this nation's economic health." Whether that argument resonates with skeptical Republican lawmakers will determine whether the defense requests move forward as currently structured or face significant modifications before reaching a vote.
