Among the intersections between [Lee Harvey] Oswald and the CIA, his time as a young Marine at the Atsugi naval air facility in Japan in 1957 is high among them. Atsugi was a launching pad for U-2 spy flights over the Soviet Union and was also a hub of the CIA's research into psychedelic drugs. A CIA memo titled 'Truth Drugs in Interrogation' revealed the agency practice of dosing agents who were marked for dangerous overseas missions," wrote author David Talbot in "The Devil's Chessboard." A new document released in full last week relates directly to Oswald's time at Atsugi, revealing details about the CIA's response to testimony from a former agency accountant that the spy service had employed Oswald " who went on to be a gunman in the assassination of President John F. Kennedy in 1963. The CIA's claim to have had no contact with Oswald is undercut by the fact that George de Mohrenschildt, a CIA asset, became close friends with Oswald in the months before the assassination. According to documents found in the newly declassified files, at the same time as his trip, the CIA's Domestic Operations Division ran a search on de Mohrenschildt, "exact reason unknown," according to two documents created by a CIA analyst included in last week's declassification. The covert arm of the division was run at the time by E. Howard Hunt, a black ops specialist who confessed later in life to learning ahead of time of a conspiracy to assassinate Kennedy that involved high-level figures in the CIA.
