1975: Former U.S. Attorney General John N. Mitchell and former White House aides H. R. Haldeman and John Ehrlichman (the latter two are seen here in 1973) are sentenced to prison for their roles in the Watergate scandal. All three men were initially sentenced to between two and a half and eight years in prison on conspiracy, obstruction of justice and perjury charges. In 1977, the sentences were commuted to one to four years and they would all serve less than two years in prison before being released.
