Watergate came to encompass an array of clandestine and often illegal activities undertaken by members of the Nixon administration, including bugging the offices of political opponents and people of whom Nixon or his officials were suspicious; ordering investigations of activist groups and political figures; and using the Federal Bureau of Investigation, the Central Intelligence Agency, and the Internal Revenue Service as political weapons. The use of the suffix "-gate" after an identifying term has since become synonymous with public scandal, especially political scandal.
