A bungled 1972 burglary at the Democratic National Committee's office in the Watergate complex exposed a White House apparatus of dirty tricks, law-breaking and cover-up. Two years later, President Richard M. Nixon, facing impeachment, resigned. President Gerald R. Ford pardoned him of any wrongdoing a month later.
