Trump COVID-19 Diagnosis Raises Issue of Continuity of Government VOA News The new realities in Washington have once again pushed the issue of continuity of government to the forefront. The 25th Amendment to the Constitution of the United States details the process by which the president or vice president are replaced in the event they are unable to execute their duties. Reasons to replace the head of state or the vice president, who is the highest-ranking official in the presidential line of succession, are death, dismissal from office, resignation or incapacitation. Examples include the November 1963 assassination of U.S. President John F. Kennedy and the 1974 resignation of then-President Richard Nixon amid the Watergate scandal. Discussion of the 25th Amendment was renewed after the announcement early Friday that President Donald Trump had tested positive for COVID-19, the disease caused by the coronavirus. First lady Melania Trump has also tested positive for COVID-19. Trump is experiencing "mild symptoms" of the disease, the White House said Friday. Vice President Mike Pence and his wife, Karen Pence, tested negative for the virus, a spokesman said Friday. .
