In 2014, the Assassination Archives and Research Center held a conference on the occassion of the 50th Anniversary of the release of the Warren Commission Report. The highlight of the conference was a statement by Cuban exile leader Antonio Veciana.
"On November 22nd, 1963, President John F. Kennedy was assassinated in Dallas. In reality, what happened that day was a coup d’état. President Kennedy’s death was a result of a conspiracy planned by CIA operatives and supported by a handful of high-ranking military officers and members of the Mafia. The conspirators believed that the President was a traitor who had jeopardized national security by established a foreign policy of dialogue and conciliation with the traditional enemies of the United States. I want to unequivocally state that Maurice Bishop was David Atlee Phillips. Here are the factors that point to a conspiracy. I traveled to Dallas at the end of August or beginning of September of 1963 to meet with Maurice Bishop, my CIA handler. We had agreed to see each other in the lobby of a downtown Dallas bank. There, I observed Bishop with a young man I later identified without a doubt as Lee Harvey Oswald. This encounter was unplanned. It would not have happened had I not arrived to the interview 15 minutes before Bishop expected me."
Below is the full transcript of Veciana's statement.
