President Trump and Defense Secretary Pete Hegseth are actively pressing Republican lawmakers to approve a substantial $350 billion defense funding increase through a budget reconciliation bill. This strategy aims to bypass the 60-vote threshold required for regular spending bills in the Senate, allowing for a significant boost to the Pentagon's budget. Trump envisions a total defense budget of $1.5 trillion, comprising a $1.15 trillion base budget and the additional $350 billion from reconciliation.
Hegseth has engaged in direct conversations with senior House Republicans, including committee chairs, to advocate for this funding. The push also comes as the administration is expected to submit a supplemental funding request to backfill munitions depleted by U.S. military operations, particularly in Iran and Venezuela. Initial estimates for this supplemental were around $200 billion, but have reportedly been scaled back to between $80 billion and $100 billion.
However, the plan faces significant hurdles. Some Senate Republicans, like Mitch McConnell and Susan Collins, have expressed skepticism about relying on reconciliation for defense funding, with McConnell stating it is "not an option." Senate Majority Leader John Thune has also indicated uncertainty about securing the necessary votes. Democrats, led by figures like Sen. Jack Reed, are resistant to approving supplemental funding for military actions without explicit congressional authorization, citing constitutional requirements and concerns about subsidizing ongoing conflicts.
Democrats also point to the already substantial proposed defense spending, with Sen. Tim Kaine noting that a potential 40% increase in defense investment in one year would be "very hard" to support. The cost of the conflict in Iran is estimated to be in the mid-$30 billion range, with total costs likely higher when considering repairs to military outposts. The administration's reluctance to submit the supplemental request may stem from concerns about public disapproval of the prolonged conflict.
