The razor-thin Republican majority in the House of Representatives is facing growing uncertainty as Republican congressmen run for Donald Trump’s Cabinet.

Congresswoman Victoria Spartz, a Republican from Indiana, announced Monday that she will no longer “sit on committees or participate in the (Republican) caucus” so that she could devote more time to the newly created Department of Government Efficiency (DOGE). , which is led by Elon Musk and Vivek Ramaswamy.

“I remain a registered Republican but will not sit on committees or participate in the caucus until I see Republican leadership in Congress. I don’t have to participate in circuses. I’d rather spend more time helping @. DOGE and @RepThomasMassie to save our republic as ordered by the American people,” she said in a post on X.

In another post, Spartz added: “@realDonaldTrump, @elonmusk and @VivekGRamaswamy are our only hope of draining the swamp through reconciliation and we can raise more than $2 trillion to fully offset tax cuts. The swamp is very deep, @DOGE!”

While some Republicans were confused by Spartz’s decision on Monday, it reportedly came in response to the House GOP Steering Committee failing to give her a coveted post on the House Ways and Means Committee, sources told Politico.

Newsweek has contacted Congresswoman Spartz via email for confirmation.

Spartz’s decision could jeopardize the narrow Republican majority in the House of Representatives while other Republican members of the House of Representatives are being tapped for positions in Trump’s Cabinet.

That includes Matt Gaetz, who has already resigned after being selected for the attorney general position, from which he later withdrew. Meanwhile, Reps. Mike Waltz of Florida and Elise Stefanik of New York are in line to be national security adviser and U.S. ambassador to the United Nations, respectively. Rep. Lori Chavez-DeRemer of Oregon was also named labor secretary.

Starting in January, Republicans will control the House of Representatives with a narrow majority of 220 seats compared to Democrats’ 215 seats, but a simple majority of 218 votes is required to pass legislation in the House. If individual MPs are absent due to illness or other reasons, the majority hurdle drops.

Waltz has already tendered his resignation, and combined with Gaetz’s resignation and the possibility that Rep. Spartz refuses to meet with Republicans, as well as the confirmation of Stefanik and Chavez-DeRemer to Cabinet posts, the Republican majority could collapse and threaten their chances of advancement Trump’s agenda.

Given these concerns, Republican senators are reportedly pushing to complete work on the overdue annual budget legislation before Trump takes office on January 20 to prevent it from stalling in the House of Representatives and potentially leading to a government shutdown that has Republicans Plan to secure the US-Mexico border could divide and drain Trump of energy.

But Speaker Mike Johnson has insisted on delaying the annual spending bills until March next year – something Republican senators say is a mistake.

“I hate it, I think it’s a mistake,” Sen. Kevin Cramer said of the plan, according to The Hill. “Speaking of rebellious House members, House Republicans, I think they are making a mistake by forcing the CR into March,” he added, referring to the continuing resolution. “I think this is a bad strategy. I just think it would have been a lot better to win the game.”

Meanwhile, new Senate Budget Committee Chairwoman Susan Collins has proposed an alternative approach: a temporary funding measure that would only last until mid-January to avoid potential chaos.

“The House is still thinking about mid-March… This senator wants to have it ready by mid-January before the new president is sworn in,” Collins told reporters when discussing how long the stopgap measure should take.

“I think that’s in both (Trump’s) interest and the country’s interest,” Collins added.

New Senate Majority Leader John Thune expressed support for Collins’ proposal but acknowledged the need for House approval.

“I would like to be able to clear the decks,” Thune told The Hill. “It’s about: What is the art of the possible and particularly in terms of what is achievable? We have to get it passed, not just through the Senate, but also through the House.”

Johnson has already faced challenges managing the GOP’s narrow majority in the current congressional term. The House speaker relied on Democratic votes to avoid a government shutdown and pass legislation to help Ukraine.

Meanwhile, Danielle Vinson, a professor of politics and international affairs at Furman University in South Carolina, previously suggested that hardline factions of the Republican Party could complicate Johnson’s ability to unite the Republican Party and pass legislation.

“Even if Republicans return to full strength after a special election, they will only have 220 seats,” Vinson said Newsweek earlier this month.

“It should make Mike Johnson’s life interesting, especially on issues like raising the debt limit or the budget, where members of the Freedom Caucus have been stubborn in the past. They have refused to support their own party leadership unless they have implemented major spending cuts or similar deficit reduction.”

Charles Bullock, a political science professor at the University of Georgia, added that the GOP leadership in the House must be “diligent” about getting members to vote.

“At a minimum, the GOP whip organization needs to be precise in the count and careful to engage members in roll calls,” Bullock said Newsweek.

“Against a united Democratic front, just a few Republican absences or members not wanting to vote on a particular bill could cost the GOP. Roll calls could remain open longer as leadership twists its hands, drags reluctant members to the ground, or waits for delayed flights from California.”
