Memo claims JFK requested CIA share UFO data days before his death

Letter dated November 12, 1963 , allegedly requested CIA brief him about 'all UFO intelligence' The recipient's name was redacted, but John McCone headed the department at the time.

The memo was obtained by William Lester , who claimed it was released to him under the Freedom of Information Act while researching his 2011 book A Celebration of Freedom: JFK and the New Frontier .

It stressed the importance of knowing what objects in the skies are unknown in the event the Soviets mistake a UFO as America spying on its defenses.

The letter has not appeared anywhere but in Lester 's book, leading some experts to question its authenticity.

The order gave the director of national intelligence and the attorney general 15 days to develop a plan to declassify the remaining documents. It is not clear when the records will actually be released. JFK was assassinated in downtown Dallas on November 22, 1963 , as his motorcade passed in front of the Texas School Book Depository building. Gunman Lee Harvey Oswald , 24 , shot from a sixth -floor sniper's perch, and was himself gunned down two days later . The Warren Commission concluded Oswald acted alone, but conspiracy theories have run riot ever since..
