Charles Wendell Colson, generally referred to as Chuck Colson, was an American attorney and political advisor who served as Special Counsel to President Richard Nixon from 1969 to 1970. Once known as President Nixon's "hatchet man", Colson gained notoriety at the height of the Watergate scandal, for being named as one of the Watergate Seven and also for pleading guilty to obstruction of justice for attempting to defame Pentagon Papers defendant Daniel Ellsberg. In 1974, Colson served seven months in the federal Maxwell Prison in Alabama, as the first member of the Nixon administration to be incarcerated for Watergate-related charges.
