Cryptonym: LPOVER
Bill Kelly's review of Joan Mellen's "Our Man in Haiti": http://jfkcountercoup2.blogspot.com/2012/11/the-addendum-to-our-man-in-haiti.html
Paul David Pope in a memoir of his father, Gene Pope, the Enquirer’s publisher, had worked for the CIA since his twenties when he served at the Italy desk, psy ops. He left the CIA to serve in Korea. After Pope bought the failing New York Enquirer with a loan from mobster Frank Costello and transformed it into the National Enquirer, CIA hovered as an editorial presence…So the National Enquirer joined Reader’s Digest, Conover Mast Publications, to which CIA assigned the cryptonym LP/OVER, and respectable publishing houses like Farrar, Starus & Giroux, as media entities cooperating with CIA.”
