U.S. White House aide.

An advertising executive in Los Angeles (1949–68), he managed several of the campaigns of Richard Nixon, including Nixon's 1968 presidential campaign. Named White House chief of staff, he became known as the "Iron Chancellor" for his efficient management of the White House and his close control of access to the president. Along with John D. Ehrlichman, he was one of Nixon's closest advisers. He participated in the cover-up of involvement by White House officials in the Watergate break-in (see Watergate scandal) and helped carry out other "dirty tricks" during the 1972 campaign. Forced to resign in 1973, he was tried and convicted in 1975 for conspiracy, perjury, and obstruction of justice; he served 18 months in prison.
