BRANDON — Incoming U.S. Senate Majority Leader John Thune (R-South Dakota) signaled Tuesday he’s willing to push back against potential attempts by President-elect Donald Trump to expand presidential power over federal spending.

“Every president is going to come in and try to do as much as they can by executive action as possible,” Thune said. “Congress, in some cases, is going to be the entity that sometimes will have to put the brakes on.”

Thune spoke Tuesday to the Brandon Valley Area Chamber of Commerce and also took questions from reporters. He said Republicans in Congress will work with Trump to achieve shared policy goals.

“The things we want to achieve at present are by and large the same,” Thune said. “How we get there is another matter, and we’ll have to work through that.”

Trump’s pick for his budget director, Russ Vought, served in the same role during the first Trump administration. Vought has since outlined an aggressive vision for presidential power in Project 2025, a 922-page document from the conservative-leaning Heritage Foundation.

“The President should use every possible tool to propose and impose fiscal discipline on the federal government.” Vought wrote. “Anything short of that would constitute abject failure.”

Trump has meanwhile tried to assert greater control over the Cabinet selection process, calling for the Senate to recess the chamber early next year so he can appoint whoever he wants without having to go through the confirmation process.

Thune said Tuesday he plans to immediately begin committee hearings on Cabinet nominees when Congress is sworn in on Jan. 3, 2025.

That’ll give the Senate a head start vetting Trump’s nominees before his inauguration on Jan. 20. After Trump is sworn in, Thune expects some nominations to quickly hit the floor of the Senate.

“The committees can’t report them out until the president is officially sworn in and they’re officially nominated,” Thune told the audience Tuesday in Brandon. “But they could do hearings.”

Thune told South Dakota reporters after the event that even though some questions have been raised about nominees, they “deserve a fair process” where senators question them on their background, qualifications and whether they “ought to be in these really important positions.”

Thune said he has not taken recess appointments off the table if Democrats try to obstruct or delay the confirmation of nominees when they reach the Senate floor, “particularly if they’re well regarded and they have bipartisan support.”

Top priorities for Republican senators heading into the new session of Congress, Thune said, include extending Trump’s 2017 tax cuts and securing the nation’s southern border.

Thune said he plans to begin drafting a budget reconciliation resolution to push an extension of the 2017 Tax Cuts and Jobs Act, key provisions of which expire at the end of 2025. The reconciliation process allows tax and spending bills to pass the Senate with 51 votes, instead of the 60 needed for most Senate legislation. Republicans will control 53 seats in the new Senate and will also control the House.

Failing to extend the tax cuts would lead to a $4 trillion tax increase, Thune said.
