Vallee also told Black that he later worked with the CIA at a camp near Levittown, Long Island, helping to train Cuban exiles to assassinate Fidel Castro.[173] Oswald participated in a CIA training camp with Cuban exiles by Lake Pontchartrain, near New Orleans.[174] Vallee’s close CIA connections, like Oswald’s, help to explain how he, too, came to be employed at a site over a presidential parade route. Thomas Arthur Vallee and Lee Harvey Oswald, two men under the CIA’s thumb for years, were being set up, one after the other, as scapegoats in two prime sites for killing Kennedy.
