Thanks--excellent links. Halperin is another name that keeps coming up. There's lots on him in Powell's book on the Institute for Policy Studies. Also, in 1969 J. Edgar Hoover suspected Halperin of being responsible for leaking sensitive information on Nixon's bombing of Cambodia to the press (
". . .on May 8 1969, New York Times reporter William Beecher wrote that 'according to Nixon administration sources,' American B-52 bombers had raided several Vietcong and North Vietnamese supply dumps and base camps in Cambodia. . .Hoover could not identify the leaker. He could only conjecture as to the source, advising Kissinger. . .that national security aide Morton Halperin could have leaked this information, on the grounds that Halperin 'knew [William] Beecher and that he [Hoover] considered [Halperin] a part of the Harvard clique and, of course, of the Kennedy era'. . .After leaving the NSC staff, Halperin and another wiretapped NSC aide, Anthony Lake, joined the campaign staff of Democratic presidential aspirant Senator Edmund Muskie of Maine. . .Hoover. . .reported on proposed speeches and article's of the administration's critics, about Lake's intention 'to work with Senator Fulbright in opposing the war'. . .": Athan Theoharis and John Stuart Cox,
