Defense Secretary Pete Hegseth is on Capitol Hill urging Congress to approve a $350 billion funding increase for the Pentagon, as the war in Iran continues with no end in sight, NPR reported on July 21, 2026.

The White House is seeking the $350 billion through a process called budget reconciliation, which would let Republicans pass the spending with a simple majority rather than the 60 votes normally needed in the Senate. The money would serve as supplemental funding for the Iran war, AP News reported on July 14. That $350 billion would come on top of $1.1 trillion in existing defense spending, according to The New York Sun.

The Pentagon has separately requested about $80 billion in supplemental funding, mostly to cover Iran war costs, AP News reported on June 22. Republicans have been weighing the $350 billion increase to match the White House request, which could move through the reconciliation process, according to AP News.

The Hill visit follows a July 14 briefing that Speaker Mike Johnson arranged for House Republicans at the Pentagon with Hegseth, The Hill reported.

The funding push is running into growing congressional resistance to the Iran conflict. On July 14, Senate Democrats blocked a $1.15 trillion annual defense policy bill, citing frustration with the Iran war and President Trump, Reuters reported. Weeks earlier, on June 23, the Senate approved a resolution to halt the Iran conflict, the first time the Senate passed such a war powers resolution, according to AP News.

The $350 billion request is part of the broader fiscal year 2027 defense budget cycle, which has already drawn significant congressional testimony. Hegseth and Air Force Gen. Dan Caine, chairman of the Joint Chiefs of Staff, testified together at a House oversight hearing on the defense budget, DOD News reported on June 10, 2025. Hegseth separately told a Senate Appropriations subcommittee that shipbuilding, Golden Dome, and nuclear deterrence are key parts of the DOD budget request, DOD News reported on June 11, 2025. Navy leaders testified on the FY27 budget request on May 20, 2026, according to DOD's FY2027 budget page.

The broader context here is a defense budget pulled in several directions at once. The reconciliation track for the $350 billion Iran supplemental would let Republicans bypass the 60-vote Senate threshold, a key procedural advantage since Democrats have already used the defense authorization bill to register objections to the war. The Senate's passage of a war powers resolution, even if it does not become law, signals that the Iran conflict has become a political liability for the administration on Capitol Hill.

The split between the $80 billion supplemental and the $350 billion reconciliation request reflects a two-track strategy the White House is pursuing: immediate war-cost reimbursement through traditional supplemental appropriations, and a larger structural increase through reconciliation. Whether House Republicans can hold together a majority for the reconciliation package, and whether $1.1 trillion in baseline spending plus $350 billion in new money can survive a floor vote, are the immediate questions Hegseth faces in his Hill meetings.

The White House budget request frames the $350 billion as tied to ongoing Iran operations. NPR described the conflict as flaring up with no end in sight, which aligns with the Senate's June war powers vote and the Democratic blockade of the defense policy bill in July. Hegseth's testimony that shipbuilding, Golden Dome, and nuclear deterrence anchor the FY27 request signals that the Pentagon is pushing for the supplemental to fund war costs while the base budget continues to invest in longer-term strategic priorities.
