George Joannides
Joannides was instrumental in concealing the CIA's connection to Lee Harvey Oswald
Called out of retirement to be the CIA liason to the House Select Committee on Assassinations, George Joannides never disclosed that he had supervised the DRE, The Cuban Student Directorate, who in 1963 played an antagonistic role in establishing Lee Harvey Oswald's legend as sympathizing with Castro, when in fact Oswald was a soldier in the secret war against Fidel Castro.
