The Trump administration's ambitious budget proposal has landed back in the House of Representatives, where it faces mounting resistance as lawmakers ponder the implications of the bill ahead of a looming July 4 deadline. Despite narrowly passing in the Senate with a tie-breaking vote from Vice President JD Vance, GOP support in the House appears fragmented, putting the legislation’s future in jeopardy.

Speaker Mike Johnson had hoped for a swift vote on Wednesday, but dwindling attendance on the House floor revealed the lack of needed support. Many Republican lawmakers had already exited as it became clear that the measure could not even pass a simple procedural step. The earlier version of the bill was initially approved by just a single vote in May. Now, the revised proposal – containing controversial amendments that some Republicans find objectionable – faces complications reconciling with the Senate's version.

President Trump, aiming to rally support for the bill, held multiple meetings with House Republicans on Wednesday, but came away with little success. Lawmaker Ralph Norman from South Carolina stated, “There won't be any vote until we can satisfy everybody,” and indicated an existing dissent among about 25 Republicans. With the margin of error slim, losing just a few votes poses significant risk for the bill’s passage.

Key issues holding up progress include whether the legislation will exacerbate the growing US national deficit and impact healthcare services. Estimates from the Congressional Budget Office (CBO) suggest the Senate's bill could add an alarming $3.3 trillion to the deficit over the next decade, escalating concern among fiscally conservative members within the House Freedom Caucus, who are expressing willingness to vote the bill down. Congressman Chip Roy, firmly aligned with this faction, voiced apprehension about meeting Trump's deadline.

On the other side, Representatives from low-income districts stress the bill's harmful cuts to Medicaid and other essential services. They fear that these reductions will adversely affect their constituents and lead to unfavorable election results in 2026. Congressman David Valadao has made it clear he won’t back a bill that undermines Medicaid stability or healthcare funding.

In parallel, some Republican lawmakers, like Randy Fine from Florida, are signaling a willingness to support the bill despite reservations, voicing that “we can't let the perfect be the enemy of the good.” Yet, key provisions that reduce taxpayer deductions for state and local taxes (SALT) have also emerged as a significant point of contention, with the proposed changes sparking additional pushback among House members.

As Republicans navigate these treacherous waters, the stakes remain high for the president and his legislative agenda, making it potentially one of the defining moments of his second term.
