Who was the first unelected US President in history?
After the Watergate scandal, Richard Nixon was forced to resign, and his vice president, Gerald Ford, ascended to the presidency. Even though this was not the first time a vice president assumed the mantle of presidency, Gerald Ford’s case was special because he was not even elected as vice president. Ford was assigned the vice presidency through the 25th Amendment, after his predecessor Spiro Agnew had to resign due to his own scandal (separate from Watergate).
After becoming president, Gerald Ford controversially pardoned his predecessor Richard Nixon for his involvement in the Watergate scandal.
