Two days ago, former Washington Post staffer and author of the book "Our Man in Mexico: Winston Scott and the Hidden History of the CIA," asked President Obama to help release records on former CIA undercover officer George Joannides, chief of the psychological warfare operations in Miami in 1963.
The records from 1963 and 1978 are being kept secret on grounds of National Security.
In 1978, Joannides was called out of retirement to serve as the CIA's liaison to the congressional JFK investigators. He said nothing about his undercover mission in 1963, even when asked for records about Oswald's contacts with his intelligence-gathering network. G. Robert Blakey, the Notre Dame law professor and former federal prosecutor who ran the probe, says Joannides' actions constituted obstruction of Congress, a felony. Joannides died in 1990 having never been questioned by JFK investigators. His Washington Post obituary described him only as a "Defense Department lawyer."
