Senate Republicans are planning to reverse many of Joe Biden’s final actions in office after the second inauguration of President-elect Donald Trump.

According to Axios, Senate Majority Leader John Thune (R-S.D.) said that he has a “fairly lengthy list” of regulations and other measures introduced by Biden after the 2024 election in early November that Republicans will attempt to reverse after President Trump is sworn back into office.

Such reversals would be made under the Congressional Review Act (CRA), which gives Congress until mid-May to undo many of Biden’s lame-duck actions. The law allows Congress to pass resolutions with filibuster-exempt majority votes in both houses of Congress, but the votes must occur after the first 15 legislative days of a new Congress; this means that such votes cannot happen until late January or early February. The deadline for CRA resolutions is 60 days into the new Congress.

In 2017, then-President Trump and the Republican majority in the 115th Congress used the CRA to repeal 16 rules enacted near the end of the Obama Administration. In response, the Biden Administration and the Democratic majority in the 117th Congress used the law to repeal just three resolutions passed at the end of the first Trump presidency.

Senator Ted Cruz (R-Texas) plans to introduce three different resolutions repealing Biden’s actions on cryptocurrency, energy, and internet access. Other rules that may be targeted by the new Republican Congress include the California-inspired carbon emissions rule, forcing auto manufacturers in the state to have 100% of new cars be zero-emission by the year 2035.

“We are looking for lots of opportunities in that space and trying to argue with the [Senate] parliamentarian,” said Thune at an event hosted by the American Petroleum Institute (API). “The whole California waiver issue … was such a radical regulatory overreach.”
