Efforts by the Department of Government Efficiency (DOGE) have been popular among conservatives, with many Republican lawmakers being eager to permanently codify its plans for spending reductions.

However, other GOP senators are refusing to unconditionally endorse DOGE's activity and may even block some of the department's recommendations. 

Sen. Susan Collins open to codifying "some" of DOGE's cuts

According to The Hill, those tempering expectations include Senate Appropriations Committee Chair Susan Collins, who told the website last week that "it could be possible that, after careful consideration, we would decide to codify some" of DOGE's cuts.

Nevertheless, the Maine Republican lawmaker was quick to stress that voters shouldn't expect an "across the board" codification of what DOGE has put forth.

Meanwhile, South Dakota Republican Sen. Mike Rounds suggested during an interview with Dakota News Now on Tuesday that there are concerns over DOGE's pace.

"It's moving a lot faster than most of us thought that it would. We want to make sure that we have an input into it,"  Rounds explained.

"We want to make sure that as members of the Senate, when we find something that’s not right, we can get it fixed as soon as possible," he continued.

Rounds acknowledged that "[t]he American people have said, one way or another, we’ve got to get this spending under control."

“So we’re going to try to help the president wherever we can to get it under control, but we’re also going to be a double check where there is damage being done that should not be done.”

Sen. Jerry Moran points to filibuster rule as an obstacle

Meanwhile, Kansas Republican Sen. Jerry Moran stressed that the filibuster makes passing legislation in the Senate more challenging than in the House.

"We have to pass bipartisan bills. You can’t pass an appropriation bill without 60 votes," Moran declared before adding that both Republicans and Democrats "always have tried to pass bipartisan bills."

The Hill noted that Alaska Republican Sen. Lisa Murkowski has been overtly hostile to some of DOGE's activity, such as its decision to curtail funding for the United States Agency for International Development (USAID).

Murkowski also complained to reporters last week that some Republicans have been "cowed into not speaking up" about DOGE due to fear of angering President Donald Trump and Elon Musk.
