The correct answer is be impeached.
President Richard Nixon was never technically impeached, even though his involvement in the Watergate scandal made him look guilty of committing a crime. Instead of facing an impeachment trial lead by the US Congress, Nixon decided to resign from the presidency during the middle of a term. This was to avoid possible impeachment trials and to put the Watergate scandal behind him. He is the only president to ever willingly resign from the presidency. This resulted in Gerald Ford becoming president.
