In Washington D.C., Senate Republicans faced a significant setback on June 26, 2025, as Senate Parliamentarian Elizabeth MacDonough ruled against several key provisions in their proposed budget reconciliation bill [1][2]. The decision impacts the GOP's strategy to pass the legislation through a party-line vote, bypassing the usual 60-vote threshold [2].

MacDonough, who adjudicates procedural disputes in the Senate, disqualified multiple health care-related provisions that were central to the Republican plan for cutting federal spending [1][2]. These included:

Restrictions on Medicaid funds for individuals without verified immigration status Changes to reimbursement contracts with pharmacy benefit managers (PBMs) Limitations on states' use of health care provider taxes for federal Medicaid funding New restrictions on eligibility for Affordable Care Act funding [2]

The rejected provisions were projected to save between $200 billion and $300 billion over a decade, according to Matthew Fiedler, a health care policy expert at the Brookings Institution [2]. This development poses a challenge for Republicans, who had planned to use these savings to offset the costs of making former President Trump's tax cuts permanent [1].

Senate Republican leaders now face the task of revising their bill to comply with reconciliation rules while maintaining enough support to secure 50 votes [3]. Despite the setback, senators plan to modify the provider tax provision to meet the parliamentarian's standards [3].

The parliamentarian's decision does not determine the final content of the legislation but rather ensures that the text adheres to Senate rules regarding the filibuster [1]. As Republicans aim to pass the bill with a simple majority, they must now navigate these procedural hurdles while balancing their policy goals and fiscal constraints.

This development adds a layer of complexity to the GOP's legislative agenda and may impact the timeline for passing their comprehensive domestic policy bill, dubbed the "One Big Beautiful Bill" [2].
