In his first 100 days, President Trump has been taking advantage of the Congressional Review Act, a law which allows Republicans to basically wipe out everything done in the final weeks of the Obama Administration.

Republicans have reversed several last-minute regulations that were pushed through just days before Trump took office. The administration has been bragging about the legislative victories leading up to Saturday’s 100 day mark, highlighting the President’s 13 reversals.

“You see that this president has done a lot in 100 days,” counselor Kellyanne Conway said on Tuesday, specifically citing these cases. “12 or 13 roll-backs of Congressional Review Acts … We are going to keep plowing ahead.”

The Congressional Review Act (CRA) was enacted by Congress in 1996, and signed into law by President Bill Clinton in March of that year. This Act gives Congress 60 legislative days to reverse any rule imposed by a president with a simple majority vote.

Before the Trump administration, the CRA was only used on one occasion to overturn a rule in 2001. In that case, President George W. Bush overturned an Occupational Safety and Health Administration rule that addressed injuries in the workplace.

Congressional Republicans still have until early May to remove Obama-era regulations that were put in place after June 2016.

The continuous use of the CRA by President Trump has given his administration several legislative victories to show off in wake of their failed attempt to repeal ObamaCare.

White House Director of Legislative Affairs Marc Short recently told reporters, “There are several more that we hope to sign before this window closes on April 28.”

The White House has called the reversed rules “unnecessary.”

Along with everything else Trump does, the left has criticised these actions.

“All told, Trump’s legislation will provide businesses with more than $7 billion dollars in giveaways over the next decade while causing a net loss in jobs, millions in reduced wages, and the elimination of important consumer protections,” Sam Berger, an author at the liberal-leaning think tank, said.

The 13 rules that have been rescinded include a measure signed in February which overturns a stream protection rule from the Department of Interior that would have restricted what mountaintop mining firms could dump into nearby waterways.

Also, on March 31, Trump overturned a Labor Department rule that limited how many unemployment applicants states can subject to drug testing. An April 3 measure eliminates worker safety regulations aimed to track and reduce workplace injuries and deaths.

Most recently on April 13, Trump nullified a Department of Health and Human Services rule that allowed states to withhold federal family planning dollars from clinics that provide abortion services.
