Trump budget seeks $1.5 trillion defense boost, cuts domestic spending

President Donald Trump’s fiscal 2027 budget would send defense spending to $1.5 trillion, a roughly 42% increase from 2026 and the first time base defense funding has crossed the $1 trillion mark. The same request would cut nondefense spending by about $73 billion, or 10%, putting domestic programs squarely in the crosshairs as the White House argues for a sharper national-security tilt.

The numbers are now moving from proposal to hearing room. Russell Vought, the White House budget director, testified before the House Budget Committee on April 15, 2026, in a session titled The President’s Fiscal Year 2027 Budget Request. He was scheduled to appear again on April 16 before the Senate Budget Committee, which labeled its hearing The President’s Fiscal Year 2027 Budget Proposal. The hearings put Vought at the center of the administration’s attempt to sell the budget as both a fiscal plan and a political statement about Trump’s priorities.

The stakes extend beyond the defense account. The budget would reduce nondefense spending by roughly $73 billion, with cuts hitting domestic programs that fund areas such as health research, heating assistance and other civilian priorities. That tradeoff is already sharpening the fight in Washington, where Democrats have accused the administration of slashing domestic programs while testing the boundaries of Congress’s power of the purse.

The timing matters as much as the topline figures. House and Senate appropriators are expected to begin marking up the 12 fiscal 2027 appropriations bills after the budget hearings, turning the White House request into the starting point for a much broader spending fight. For Trump allies, the proposal is a blueprint for the administration’s governing agenda. For critics, it is an opening bid that tries to lock in military expansion while forcing Congress to absorb the political cost of domestic cuts.

Questions about how the administration would pay for the military buildup are growing alongside the budget itself. The plan has drawn fresh scrutiny over unresolved costs tied to the Iran war, and Vought said he could not yet estimate that figure. That uncertainty gives Congress an immediate budget test: whether to accept the White House’s defense surge first and sort out the price later, or demand a fuller accounting before the appropriations process moves ahead.
