The Trump administration is encountering stiff resistance from Republican fiscal conservatives as it pushes for a massive $1.5 trillion defense budget coupled with tens of billions of dollars to fund the ongoing Iran conflict. Despite personal appeals from President Trump and Defense Secretary Pete Hegseth on Capitol Hill this week, many GOP lawmakers remain skeptical of the price tag.
On Wednesday, Trump and Hegseth made a joint appearance before House Republicans, where the Pentagon chief delivered a classified briefing on the administration's military strategy. Hegseth also met separately with Speaker Mike Johnson (R-La.) to lobby for the funding package. However, the effort has so far failed to sway key fiscal hawks who question the need for such a vast expenditure at a time of rising national debt.
The administration is seeking $350 billion in supplemental defense funding as part of a third reconciliation bill, on top of a $1.15 trillion base Pentagon budget. This week, the White House also requested an additional $88 billion, primarily to replenish munitions depleted by the Iran war, including advanced precision-guided weapons whose stockpiles have been running low since before the conflict began.
The push comes amid a broader debate over defense priorities and fiscal responsibility. Critics within the GOP argue that the spending spree lacks sufficient oversight and could balloon the deficit. Some lawmakers have also raised concerns about the strategic rationale for the Iran war, especially as Trump has pursued a controversial memorandum of understanding with Tehran that has drawn bipartisan backlash.

Hegseth's repeated visits to Capitol Hill over the past month underscore the administration's difficulty in rallying support. While some defense hawks back the funding as essential for national security, fiscal conservatives are demanding offsets or spending cuts elsewhere. "We can't just keep writing blank checks," one Republican aide told The World Signal, speaking on condition of anonymity. "There needs to be a real conversation about priorities."
The Iran war funding request is particularly contentious, as it comes amid a broader reassessment of U.S. military commitments abroad. Some GOP senators have argued that Iran must retain certain missile capabilities for self-defense, a stance that has sparked bipartisan backlash. For more on that, see a GOP senator's defense of Iran's missile program. Meanwhile, former national security officials like Susan Rice have blasted Trump's Iran policy as a "surrender document," further complicating the political landscape.
Adding to the pressure, the Cook Political Report recently shifted seven House races toward Democrats, signaling potential electoral consequences for Republicans who back unpopular spending. The administration is also facing scrutiny over other issues, including a flu outbreak at Lackland Air Force Base linked to Hegseth's decision to end mandatory vaccinations. For details, see our coverage of Lackland flu cases surpassing 220 after Hegseth ends mandatory vaccination.
As the debate continues, the White House is expected to intensify its lobbying efforts, but the path forward remains uncertain. With no clear consensus among Republicans, the fate of the $1.5 trillion defense budget and Iran war funding hangs in the balance.
