I recall Haldeman, Erlichman, Ollie and AG Josh Mitchell; openly conceding they were “toast” when prosecutors filed charges against them in DC. I believe most were set aside on appeal.
Reps get no free pass in DC.
After he left the Nixon administration in April 1973, Haldeman was tried on counts of perjury, conspiracy, and obstruction of justice for his role in the Watergate cover-up. He was found guilty and imprisoned for 18 months. Upon Haldeman's release, he returned to private life and was a successful businessman and real estate developer until his death from cancer in 1993 at the age of 67.
Ehrlichman was a key figure in events leading to the Watergate break-in and the ensuing Watergate scandal, for which he was convicted of conspiracy, obstruction of justice, and perjury, and served a year and a half in prison.
After his tenure as U.S. Attorney General, John Mitchell served as chairman of Nixon's 1972 presidential campaign. Due to multiple crimes he committed in the Watergate affair, Mitchell was sentenced to prison in 1977 and served 19 months.
Ollie North was indicted in March 1988 on 16 felony counts. His trial opened in February 1989, and on May 4, 1989, he was initially convicted of three: accepting an illegal gratuity, aiding and abetting in the obstruction of a congressional inquiry, and ordering the destruction of documents through his secretary, Fawn Hall. He was sentenced by U.S. District Judge Gerhard Gesell on July 5, 1989, to a three-year suspended prison term, two years probation, $150,000 in fines, and 1,200 hours of community service. North performed some of his community service within Potomac Gardens, a public housing project in southeast Washington, DC. However, with the help of the American Civil Liberties Union, North appealed his conviction to the U.S. Court of Appeals for the District of Columbia Circuit. On July 20, 1990, the D.C. Circuit vacated North's convictions on the ground that witnesses in his trial might have been impermissibly affected by his immunized congressional testimony.
