Nixon chose to resign from presidency on August 9, 1974 because he did not want to be impeached (this means that he may be charged with crimes). So, the U.S. Congress could not impeach him. After this, Gerald Ford, his vice-president, became the President. Ford later forgave and pardoned Nixon for all of his crimes. The name "Watergate" comes from the hotel in Washington, D.C. where the first crime took place and is often associated with political scandals.
