The document summarizes key events in the Watergate scandal that ultimately led to Richard Nixon's resignation as President of the United States. It describes that Nixon refused to release White House tapes that could be used as evidence, while his Vice President Spiro Agnew resigned after pleading no contest to tax evasion charges. It also discusses the "Saturday Night Massacre" where Nixon ordered the firing of the special prosecutor investigating Watergate, leading to huge public backlash. The document concludes that tapes revealed Nixon's involvement in a cover up, causing the House to begin impeachment proceedings and Nixon to resign in August 1974, after which Gerald Ford became president and pardoned Nixon.
