War Powers Vote Meets $87.6B Iran Supplemental: Congress’s Oversight Test

On June 23, 2026, the U.S. Senate voted to approve a War Powers Resolution aimed at removing U.S. forces from hostilities with Iran. The next day, the White House—through the Office of Management and Budget—transmitted an “Estimate No. 2” supplemental request for $87.6 billion to the House, setting up a high-stakes question for appropriators: will lawmakers treat the war-powers rebuke as a funding constraint through conditions, delays, or both?

Two milestones in two days: authority first, then the money

In a statement released immediately after the Senate vote, Sen. Adam Schiff said the resolution “reaffirms Congress’ constitutional role” and is meant to end the conflict and bring servicemembers home. That reflects the core oversight point: a war-powers vote signals Congress’s constitutional role, but it does not automatically determine what funding Congress will provide next.

On June 24, OMB sent the supplemental package to House Speaker Mike Johnson. The House Appropriations Committee then confirmed the $87.6 billion package was “officially transmitted” to the committee for review—meaning this is a procedural handoff, not enacted spending.

What the $87.6B request says it would cover

OMB’s letter says most of the supplemental request is for urgent needs tied to Operation Epic Fury (OEF), including operational costs and classified programs. In the letter’s headline numbers, the request totals $87,596,238,000.

For the Iran operation, OMB lists $67.1 billion for the Department of War, including:

• $17.3 billion for operational costs
• $21 billion for munitions
• $12.1 billion for “other classified programs”

The letter also points to multiple classified-request elements across agencies. In the public table, those include (for example) an FBI account described as supporting Operation Epic Fury and “other classified needs,” and a Department of Energy item described as a classified request.

Beyond the war accounts, the public table includes several reader-relevant totals, such as:

• $768 million for the Department of Energy, primarily for the National Nuclear Security Administration for OEF-related activities
• $1.4 billion for the Ebola virus outbreak in Central Africa
• $11.1 billion for American farmers, including $10 billion in temporary economic assistance for certain crop year 2026 plantings
• $500 million for restoration and construction projects in and around Washington, D.C.
• $1 billion for the final design and construction of a modernized Penn Station in New York City
• $600 million for General Services Administration facilities (including elevator-related capital projects)
• $1 billion for the Pension Benefit Guaranty Corporation Fund

Where Congress is processing it—and what that means for oversight

The House Appropriations Committee’s confirmation matters because it means the package is now in committee review, where members can press for reporting requirements, procedural handling of classified material, and policy limits tied to what’s being funded.

The oversight-money standoff: will war powers shape the supplemental package?

As committees begin reviewing Estimate No. 2, the practical fight is whether Congress treats the war-powers rebuke as a funding constraint that shapes the bill’s conditions and timing—or whether it funds replenishment for urgent war-related costs while still asserting limits elsewhere.

What to watch next:

• Whether committee leaders attempt to separate Operation Epic Fury-related accounts from other items (like Ebola, farmers, and infrastructure) or bundle them.
• Whether negotiations produce conditions tied to oversight and implementation questions raised by the war-powers vote.
• How classified portions are handled procedurally (for example, via classified briefings or separate oversight channels) without turning the public review into a blank check.
