_Allegations of conspiracy._--Literally dozens of allegations of a conspiratorial contact between Oswald and agents of the Cuban Government have been investigated by the Commission. Among the claims made were allegations that Oswald had made a previous trip to Mexico City in early September to receive money and orders for the assassination,[C6-567] that he had been flown to a secret airfield somewhere in or near the Yucatan Peninsula,[C6-568] that he might have made contacts in Mexico City with a Communist from the United States shortly before the assassination,[C6-569] and that Oswald assassinated the President at the direction of a particular Cuban agent who met with him in the United States and paid him $7,000.[C6-570] A letter was received from someone in Cuba alleging the writer had attended a meeting where the assassination had been discussed as part of a plan which would soon include the death of other non-Communist leaders in the Americas.[C6-571] The charge was made in a Cuban expatriate publication that in a speech he delivered 5 days after the assassination, while he was under the influence of liquor, Fidel Castro made a slip of the tongue and said, “The first time Oswald was in Cuba,” thereby giving away the fact that Oswald had made one or more surreptitious trips to that country.[C6-572] [Illustration: COMMISSION EXHIBIT NO. 1400 LEE HARVEY OSWALD’S MOVEMENTS IN MEXICO CITY] Some stories linked the assassination to anti-Castro groups who allegedly were engaged in obtaining illicit firearms in the United States, one such claim being that these groups killed the President as part of a bargain with some illicit organizations who would then supply them with firearms as payment.[C6-573] Other rumors placed Oswald in Miami, Fla., at various times, allegedly in pro-Cuban activities there.[C6-574] The assassination was claimed to have been carried out by Chinese Communists operating jointly with the Cubans.[C6-575] Oswald was also alleged to have met with the Cuban Ambassador in a Mexico City restaurant and to have driven off in the Ambassador’s car for a private talk.[C6-576] Castro himself, it was alleged, 2 days after the assassination called for the files relating to Oswald’s dealings with two members of the Cuban diplomatic mission in the Soviet Union; the inference drawn was that the “dealings” had occurred and had established a secret subversive relationship which continued through Oswald’s life.[C6-577] Without exception, the rumors and allegations of a conspiratorial contact were shown to be without any factual basis, in some cases the product of mistaken identification.
