President Donald Trump is turning up the pressure on Senate Republicans — and particularly Senate Majority Leader John Thune — after another setback to key parts of the America First agenda sparked outrage among conservatives.

In a fiery post on Truth Social, Trump blasted the Senate Parliamentarian and demanded immediate action, accusing the unelected procedural official of repeatedly standing in the way of Republican priorities while benefiting Democrats.

“Senate Majority Leader John Thune should immediately fire the Parliamentarian, who treats Republicans, and everything that they stand for, horribly!” Trump wrote.

The president’s frustration comes as Senate Republicans continue struggling to push through major legislative priorities, including the SAVE America Act — a proposal conservatives argue is essential to strengthening election integrity and safeguarding American citizenship in federal elections.

For many in the MAGA movement, the latest procedural roadblocks have only intensified concerns that Republican leadership lacks the urgency needed to capitalize on the mandate voters handed Trump in his return to the White House.

Trump didn’t hold back.

He pointed directly at the origins of the Parliamentarian’s appointment, arguing that her background raises serious concerns about neutrality.

“She was put there by then Senate Majority Leader Harry Reid and Barack Hussein Obama — need I say more?” Trump posted.

The president also took aim at longtime GOP powerbroker Sen. Mitch McConnell, accusing him of preserving an establishment system that repeatedly undermined conservative priorities.

Trump argued that McConnell had little trouble cooperating with Democrats on massive spending packages while failing to fully support key Republican goals like border security.

“Republicans got NOTHING,” Trump wrote, referencing past fights over funding for the southern border wall during his first administration.

The controversy erupted after recent procedural rulings reportedly complicated Republican efforts to move portions of Trump’s agenda through the Senate at a simple-majority threshold. Conservatives have increasingly argued that technical rulings from the Parliamentarian are being weaponized to slow momentum on priorities voters overwhelmingly backed in 2024.

Trump described the official as someone with “no respect for Republicans or Republican ideology,” claiming recent decisions unfairly targeted GOP efforts.

“We have every right to change her, and should do so immediately,” Trump declared. “As long as she’s there, we will never get our desperately needed SAVE AMERICA ACT approved.”

But despite growing pressure from Trump allies, Thune quickly signaled that he has no intention of removing the Parliamentarian — a decision likely to further frustrate grassroots conservatives already skeptical of Senate leadership.

Speaking to reporters, Thune defended the role, arguing that rulings often cut both ways.

“Parliamentarian rulings break both ways,” Thune said. “You lose a few, you win a few.”

He emphasized that the position requires someone capable of serving as an impartial referee in highly technical legislative disputes.

Still, many conservatives remain unconvinced.

To them, the issue goes beyond Senate procedure — it’s about whether Republicans are willing to fight aggressively for the agenda voters elected Trump to deliver.

The timing is especially sensitive as internal divisions within the GOP continue surfacing over immigration, spending, and election-related legislation. Trump supporters argue that endless procedural delays are precisely the kind of Washington dysfunction voters rejected when they returned him to office.

Online, conservatives wasted little time voicing frustration.

“Why are Republicans always playing defense?” one commenter wrote.

Another added, “If Democrats would remove obstacles to pass their agenda, why are Republicans afraid to fight?”

For now, Thune appears unwilling to budge. But with Trump publicly turning up the heat, the pressure inside the Republican Party is only intensifying — and the battle over who truly controls the Senate’s direction may just be getting started.
