From Tim Weiner’s history of the CIA, Legacy of Ashes:
The ambassador [Henry Cabot Lodge] resented the agency’s exalted status in Saigon. “CIA has more money; bigger houses than diplomats; bigger salaries; more weapons; more modern equipment.” He was jealous of the powers held by [CIA station chief] John Richardson, and he scoffed at the caution the station chief displayed about Conein’s central role in the coup plotting. Lodge decided he wanted a new station chief.
So he burned Richardson — “exposed him and gave his name publicly to the newspapers,” as Bobby Kennedy said in a classified oral history eight months later — by feeding a coldly calculated leak to a journeyman reporter passing through Saigon. The story was a hot scoop. Identifying Richardson by name — an unprecedented breach of security — it said he had “frustrated a plan of action Mr. Lodge had brought with him from Washington, because the agency disagreed with it…one high official here, a man who has devoted most of his life in the service of democracy, likened the CIA’s growth to a malignancy, and added he was not sure that even the White House could control it.” The New York Times and the Washington Post picked up the story. Richardson, his career ruined, left Saigon four days later; after a decent interval, Ambassador Lodge moved into his house.
