Robert Blakey, the Chief Counsel of the committee, later changed his views that the CIA was being cooperative and forthcoming with the investigation when he learned that the CIA's special liaison to the Committee researchers, George Joannides, was actually involved with some of the organizations that Lee Harvey Oswald was involved with in the months leading up to the assassination. Among these organizations was an anti-Castro group, the Directorio Revolucionario Estudiantil, which was linked to the CIA (Joannides was in fact working for the CIA in 1963). Chief Counsel Blakey later stated that Joannides should have in fact been interviewed by the HCSA, rather than serving as a gatekeeper to the CIA's evidence and files regarding the assassination. He further disregarded and suspected all the CIA's statements and representations to the Committee, accusing it of obstruction of justice.
