Twenty-second Amendment to the United States Constitution
Some argue that the 22nd Amendment and 12th Amendment bar any two-term president from later serving as vice president as well as from succeeding to the presidency from any point in the presidential line of succession. Others contend that the original intent of the 12th Amendment concerns qualification for "service" (age, residence, and citizenship), while the 22nd Amendment, concerns qualifications for "election", and thus (strictly applying the text) a former two-term president is still eligible to "serve" as vice president (neither amendment restricts the number of times an individual can be elected to the vice presidency), and then succeed to the presidency to serve out the balance of the term (though prohibited from running for election to an additional term).
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.
