From a “Politico” article, referring to Haldeman’s book “The Ends of Power”:
Haldeman suggested that Nixon used the phrase, “the whole Bay of Pigs thing,” as a coded reference to the assassination of President John F. Kennedy on Nov. 22, 1963. It was, he wrote, “the president’s way of reminding Helms, not so gently, of the cover-up of the CIA assassination attempts on the hero of the Bay of Pigs, Fidel Castro, a CIA operation that may have triggered the Kennedy tragedy and which Helms desperately wanted to hide.”
that all may be true, but Nixon was well within his right as P resident, based on the National Security threat that whole thing presented.
