William Matthew Byrne Jr.
He then went to work as an Assistant United States Attorney for the Southern District of California from 1958 to 1960, and was in private practice in Los Angeles for the next seven years.[citation needed] The first revelation came on April 26, 1973, when the government prosecutor disclosed that White House operatives had burgled the Beverly Hills office of Ellsberg's psychiatrist.[citation needed] The burglars, led by G. Gordon Liddy and E. Howard Hunt, were not apprehended until after they burgled the Democratic National Committee headquarters at the Watergate complex in Washington nine months later.[citation needed] On May 9, Byrne learned of yet another illegality: the FBI had secretly taped phone conversations between Ellsberg and Morton Halperin, who had supervised the Pentagon Papers study.[3] Neither Byrne nor Ehrlichman revealed this discussion about the FBI directorship to the litigants in the Ellsberg case until his visit was discovered by the press.
