1968? What The New LBJ Tapes Reveal". History News Network, January 26, 2009. Transcript from of President Johnson: "This is treason.""I know." Defense Secretary Clark Clifford considered the moves an illegal violation of the Logan Act. A former director of the Nixon Library called it a "covert action" which "laid the skulduggery of his presidency". Bryce Harlow, former Eisenhower White House staff member, claimed to have "a double agent working in the White House... I kept Nixon informed."

Johnson learned of the Nixon-Chennault effort because the NSA was intercepting communications in Vietnam. In response, Johnson ordered NSA surveillance of Chennault and wire-tapped the South Vietnamese embassy and members of the Nixon campaign. He did not leak the information to the public because he did not want to "shock America" with the revelation, nor reveal that the NSA was
