Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
First 100 days of Donald Trump's presidency
Beginning in January, the Trump administration used the 1996 Congressional Review Act (CRA) to overturn regulations—some of them major—finalized during the final months of Obama's tenure. By April 6, Trump had signed into law 11 resolutions of disapproval under the CRA, after they were passed by the Republican majority in the House and Senate. Under the Congressional Review Act, Congress can circumvent the Senate's filibuster to overturn legislation issued in the last 60 days of the previous administration.
