Some authors have speculated that anti-Castro groups wanted Kennedy killed because of the failed Bay of Pigs invasion in 1961, or that Castro himself ordered the killing given the fact that the CIA had tried to kill Castro during Kennedy's time in office. But G. Robert Blakey, chief counsel of the 1979 House Select Committee, says that neither scenario was likely.
"We went down to Cuba, and we sat in Castro's office," Blakey, now a law professor at the University of Notre Dame, told Discovery News. "He was persuasive and said that he had nothing to gain. He said "I'm dealing with a capitalist system and I'm a socialist system; the people don't make a difference.' Why would he want to kill Kennedy to get Johnson?"
