House appropriators have pushed back plans to mark up a fiscal 2027 Defense spending bill by about a month due to uncertainty over how to finance a massive surge in Pentagon funding sought by the Trump administration, according to sources familiar with the planning.

Why it matters

The delay reflects the complexity of assessing the Pentagon's funding requirements and how to finance them, especially given the ongoing U.S. and Israeli war against Iran. This uncertainty could impact the timeline and substance of the final defense budget.

The details

A tentative schedule last month called for a subcommittee markup of the Defense bill on May 15, followed by a full-committee markup on May 19. But those markups have now been delayed until June 11 and June 24, respectively, under the latest plan, which is still subject to change.

  • The original markup schedule was for May 15 and May 19.
  • The new markup schedule is now set for June 11 and June 24.

What’s next

The House Appropriations Committee will now mark up the fiscal 2027 Defense spending bill on June 11 and June 24, giving them more time to assess the Pentagon's funding requirements and how to finance them.

The takeaway

This delay highlights the challenges lawmakers face in crafting the defense budget, especially with the ongoing war against Iran adding further uncertainty to Pentagon funding needs. The final defense budget may look quite different from the initial proposal as a result of this extended review process.
