White House secretary Kathleen Chenow (see June 28-July 3, 1972) confirms the existence of the “Plumbers,” the extralegal operation tasked with finding and closing media leaks (see Late June-July 1971). According to Chenow, the unit is made up of White House and Nixon campaign aides David Young, G. Gordon Liddy, E. Howard Hunt, and Egil Krogh. [O.T. Jacobson, 7/5/1974 ] Chenow says that Nixon’s senior aide John Ehrlichman supervised the activities of the unit. She explains: “Originally the administration had wanted a study of how close the New York Times version of the Pentagon Papers (see March 1971) was to the actual documents. Then they tried to determine how the Pentagon Papers got out. That started it all, the business of looking for leaks. For a while, dying State Department leaks. They checked embassy cables and tried to put two and two together about whose desks the cables went across.” The “Plumbers” also investigated reporter Jack Anderson. Chenow says that when she was interviewed by the FBI in April, Young, White House counsel John Dean, and Dean’s aide Fred Fielding were present. She adds that when she subsequently testified before the Watergate grand jury, she was puzzled that prosecutor Earl Silbert never asked her about Ehrlichman.
