President Donald Trump escalated his public pressure on Senate Majority Leader John Thune on Wednesday, posting a forceful demand on Truth Social that Thune fire Senate Parliamentarian Elizabeth MacDonough, a move the South Dakota Republican has repeatedly refused to make.
The July 1 post marks at least the second time Trump has publicly called for MacDonough's removal, a confrontation that has exposed a widening rift between the White House and Senate Republican leadership over how aggressively to use procedural tools to advance the president's legislative agenda.
At the center of the dispute: the SAVE America Act, a voter ID bill that has stalled in the Senate because it cannot clear the chamber's 60-vote filibuster threshold. MacDonough, whose job is to determine which provisions comply with the strict budgetary rules governing reconciliation, has repeatedly blocked Republican attempts to route policy priorities through the simple-majority process. Trump views those rulings as biased. Thune views them as the cost of doing business under existing Senate rules.
Trump's Truth Social post left no room for ambiguity. Just the News reported the president wrote:
"How the Republican Senate is not firing the Parliamentarian, who was appointed by Radical Left Senator Harry Reid, and Barack Hussein Obama, is beyond me! She has been ruling unfairly against Republicans for years, and Majority Leader John Thune has the right to do it, immediately. FIRE THE PARLIAMENTARIAN NOW!"
The post frames MacDonough as a partisan obstacle installed by Democrats, a characterization Trump has leaned on before. MacDonough was appointed in 2012 by then-Senate Majority Leader Harry Reid and serves at the pleasure of the current majority leader.
Whether her appointment by a Democratic leader makes her rulings partisan is another question. Her recommendations are advisory, the presiding officer and the full Senate can override them, but Republican leaders have shown no appetite for doing so.
Thune has made his position clear on multiple occasions. When Trump privately pressed him on the matter during an earlier phone call, the majority leader did not budge. Fox News reported Thune told reporters:
"There are always people that are unhappy with some decisions that come down, and it's kind of the nature of the beast. So, you know, we will work through the process."
That measured tone has not satisfied the White House or the conservative flank of the Senate Republican conference. Public tensions between Trump and Thune have simmered for weeks, and some of the more conservative senators have sided with the president's frustration, if not always with his preferred remedy.
The friction is not limited to the parliamentarian question. Deeper fractures within the GOP conference have surfaced over Iran policy and the voter ID bill, with the White House and Senate leadership pulling in different directions on multiple fronts.
MacDonough's rulings have frustrated Republicans on several fronts. She stripped roughly $1 billion in security funding, including $220 million earmarked for a new East Wing ballroom, from a reconciliation package, ruling the spending violated the Senate's Byrd rule. That rule limits reconciliation bills to provisions with a direct budgetary impact, preventing lawmakers from using the fast-track process to pass policy changes unrelated to taxing and spending.
Breitbart reported that MacDonough concluded the ballroom funding would require a 60-vote threshold rather than a simple majority if kept in the legislation. Republican lawmakers began working to redraft language that could comply with the Byrd rule.
Beyond the security funding, MacDonough's rulings dealt a blow to GOP efforts to cut hundreds of billions of dollars from Medicaid over the next decade, a priority for fiscal hawks trying to offset the cost of extending Trump's tax cuts.
The cumulative effect has been to narrow the scope of what Republicans can accomplish through reconciliation, a sore point that has escalated steadily since the first round of rulings.
The divide among Senate Republicans on the parliamentarian question is instructive. It tracks almost perfectly with the broader fault line between institutionalists who prize Senate tradition and populists who see those traditions as obstacles to governing.
Sen. Susan Collins of Maine defended MacDonough directly. The Washington Examiner reported Collins said:
"I do not support the firing of the parliamentarian. She does an excellent job and applies the Senate rules fairly and in a nonpartisan way."
Sen. Ron Johnson of Wisconsin offered a different critique, not of MacDonough, but of the underlying problem. "She's literally not the problem," Johnson said. "The problem is we maintain the filibuster."
Sen. John Kennedy of Louisiana responded to the firing question with characteristic bluntness: "For what. Does she have a DWI or something?"
Sen. Kevin Cramer of North Dakota acknowledged the tension but sided with institutional continuity. "It's the institutional integrity, even if I'm convinced 100% she's wrong," Cramer said, as AP News reported.
On the other side, Sen. Tommy Tuberville called for MacDonough to be fired "ASAP." And Rep. Greg Steube of Florida went further, arguing Thune should have acted on day one.
"Thune has the absolute authority to remove her and replace her with somebody else. He should have done it right when he took office."
That argument, that the majority leader has unilateral authority to replace the parliamentarian, is factually correct. The parliamentarian serves at the pleasure of the majority leader. The question is whether exercising that authority would be worth the institutional cost.
The voter ID bill sits at the heart of this fight. The SAVE America Act has languished in the upper chamber because it cannot attract the 60 votes needed to overcome a filibuster. The White House has pushed to include it in reconciliation, which requires only a simple majority. MacDonough's rulings have blocked that path.
Thune has been unwilling to alter Senate rules to force the bill through. That refusal has put him at odds not only with the president but with a growing number of conservative senators who see the filibuster, or at least the parliamentarian's enforcement of it, as an impediment to delivering on campaign promises.
The bill's path remains unclear. It has shown some signs of progress, clearing the 50-vote mark as GOP defections narrowed, but the 60-vote threshold remains a hard barrier without a rules change or a successful reconciliation workaround.
Michael Thorning of the Bipartisan Policy Center offered a defense of MacDonough's role that gets at the institutional argument: "Senators know this isn't somebody playing politics."
Maybe so. But the practical result of MacDonough's rulings is that Republican voters sent a Republican president and a Republican Senate majority to Washington, and the legislative agenda keeps running into a wall erected by an unelected official whose authority rests entirely on tradition and the majority leader's willingness to defer to it.
That is a legitimate source of frustration. Trump is not wrong that Thune has the power to act. And Thune is not wrong that firing the parliamentarian would set a precedent that future Democratic majorities would exploit without hesitation.
But the current arrangement, in which the majority leader refuses to use the tools available to him, the parliamentarian blocks provisions the majority wants, and the president vents on social media, is not a governing strategy. It is a stalemate dressed up as process.
Trump has made this case before, and he will almost certainly make it again. The question is whether Thune will eventually move, or whether he will keep telling voters that the rules tied his hands while the agenda they voted for collects dust.
Republican voters did not send a majority to Washington to be governed by the Byrd rule. At some point, the people they elected have to decide whether they work for the institution or for the people who put them there.
