US President Donald Trump is facing calls for Section 4 of the 25th Amendment after he shared an expletive-laden threat to Iran on Easter Sunday.
The Vice President and a majority of the Cabinet can invoke Section 4, declaring the President 'unable to discharge the powers and duties of his office.'
If invoked, the Vice President becomes Acting President, but the President can challenge this, and Congress must decide with a two-thirds vote.
Section 4 has not been implemented, and its authors rejected claims it could be used for political purposes.
Trump's health update sparked speculation after the White House declared a press 'lid' and rumors of a hospital visit to Walter Reed National Military Medical Center.
However, the White House denied these claims, stating the President was working nonstop at the White House throughout the Easter weekend.
