John Ehrlichman

Ehrlichman was the former assistant to Nixon in charge of domestic affairs. He created the infamous "plumbers" group that was at the center of the scandal.

The team of Ehrlichman and H.R. Haldeman was known but other White House staffers as "The Berlin Wall" because they served as Nixon's gatekeepers and kept others away from him. The two men were asked to resign by the President Nixon after damaging testimony by former White House Counsel John Dean. Ehrlichman is said to have never forgiven Nixon for not pardoning him.

Ehrlichman served 18 months in prison. He was sentenced to a maximum of 25 years in prison and $40,000 in fines. Ehrlichman was later convicted of conspiracy, obstruction of justice, perjury and other charges.
