Senate Republicans are increasingly debating how aggressively they should push President Donald Trump’s legislative agenda through Congress, with some conservatives voicing frustration over recent procedural rulings from Senate Parliamentarian Elizabeth MacDonough.

Several Republican aides say support is growing among members of the GOP conference for replacing the parliamentarian after rulings blocked key conservative priorities, including funding connected to a proposed White House ballroom project and parts of the SAVE America Act, a Republican-backed election security measure.

The dispute has become part of a broader push by Trump allies to remove procedural obstacles slowing down major conservative legislation in the Senate.

President Trump publicly criticized MacDonough on social media, accusing her of political bias and arguing that Senate Republicans should fight harder to advance his agenda. His comments intensified pressure on GOP lawmakers already facing growing demands from the conservative base to deliver on issues such as election integrity, border security, and government reform.

Some Republican aides say frustration within the party is especially strong among senators aligned with the MAGA movement, who believe procedural rulings have repeatedly favored Democratic priorities while limiting conservative legislation.

At the same time, other Republican senators and aides are urging caution, noting that the Senate parliamentarian traditionally serves as a nonpartisan interpreter of chamber rules and budget reconciliation procedures.

Supporters of MacDonough point out that she has previously delivered several rulings that benefited Republicans, including decisions tied to Trump’s 2017 tax cuts and energy provisions that opened parts of Alaska’s Arctic National Wildlife Refuge to oil and gas development.

More recently, Senate Republicans also secured favorable rulings connected to a national school-choice tax credit program included in major legislation last year.

John Thune, the Senate Majority Leader, has publicly downplayed speculation about removing MacDonough, saying disagreements over parliamentary rulings are common during reconciliation fights regardless of which party controls the Senate.

Still, Trump’s criticism of establishment Republicans — including his recent endorsement of Texas Attorney General Ken Paxton over Senator John Cornyn in a future primary race — is being viewed by many Republicans as a warning that GOP lawmakers will face mounting pressure to fully support the president’s legislative goals.

Some conservatives argue that Senate rules should not stand in the way of policies they say voters overwhelmingly supported in the 2024 election. Others caution that dramatically reshaping Senate procedures could eventually backfire when Democrats regain congressional control.

Despite the internal debate, Republicans remain largely united around advancing Trump’s broader agenda, particularly on tax policy, border enforcement, election reform, and reducing federal bureaucracy as the party prepares for upcoming legislative battles in Washington.
