President John F Kennedy was shot dead because he demanded the release of top-secret UFO files from the CIA, an alien researcher has sensationally claimed.
The claim was made after US presidential Democratic candidate Hilary Clinton vowed to get to the bottom of an alleged UFO cover up high within the government.
Scott C Waring, editor of UFO Sightings Daily, posted copies to his website of a letter sent by JFK to the then head of the CIA just 10 days before he was murdered.
He wrote: “Presidential candidate Hillary Clinton doesn’t know it yet, but she does not have the power to release such information.
“CIA would kill her before she could, just like they did JFK.
“Yes, just a week before his death JFK wrote a memo to CIA to release all pertinent info to NASA, but somehow he was killed before it ever happened.
“I was the first to publish this document in my book UFO Sightings 2006-2009.”
The memo is a confirmed declassified document released by the CIA.
Mr Waring added: “JFK wrote the memo to CIA on Nov 12, 1963, then on Nov 22, 1963 he was killed.
The memo asked for a breakdown of identified and unidentified sightings the CIA was aware of.
JFK wrote: “It would be very helpful if you would have the high threat cases reviewed with the purpose of identification of bona fide as opposed to classified CIA and USAF sources.
“It is important that we make a clear distinction between the knowns and unknowns in the event the Soviets try to mistake our extended cooperation as a cover for intelligence gathering of their defence and space programs.
“I would like you to arrange a program of data sharing with NASA where unknowns are a factor.”
On the same day JKF sent a separate memo to NASA asking for “cooperation with the former Soviet Union on mutual outer space activities.”
It is understood JFK was concerned about the high amount of UFO sightings over Russia and feared the Soviets would wrongly believe it was US spying equipment.
Four days later on November 16 1963 he visited NASA at Cape Canaveral, Florida, which further fuels the conspiracists theory.
Several other alien researchers have said they support the theory on various postings on websites.
In the 1990s a document which became known as the “burned memo” surfaced.
It was allegedly received in the post by a UFO researcher called Timothy Cooper in 1999 and was said to have been sent by an unnamed CIA source who allegedly worked three from 1960 to 1974.
The alleged source claimed the document, which has never been verified as real, was pulled by him from a fire while the CIA was burning sensitive material, hence the scotch marks.
The memo had no date and referred to “Lancer”, the supposed secret service code name for JFK.
It allegedly had this message from the director of Central Intelligence: “As you must know, Lancer has made some inquiries regarding our activities, which we cannot allow.
“Please submit your views no later than October. Your action to this matter is critical to the continuance of the group.”
Sceptics claim the “burned memo” was a fake to add fuel to the conspiracy.
There have been many conspiracies surrounding JFK’s death, including those claiming CIA involvement, but not always because of UFOs.
Ex-marine misfit Lee Harvey Oswald, 24, was charged with the shooting, which he denied, but he too was shot dead by nightclub boss Jack Ruby before he could go on trial.
In November, James Files, 72, a Mafia hit man in jail for separate murders claimed in an interview that he had been a sniper on the day of JFK’s death and fired a shot at his head.
Controversially, he says there was collusion between the Mafia and the CIA to kill 46-year-old Kennedy, claims which could lead to him being called to give testimony on oath in Washington.
The Vietnam war veteran was part of the CIA team that trained a militia for the ill-fated Bay of Pigs invasion in Cuba in 1961, which turned many in the agency against Kennedy when he called a sudden halt to the clandestine operation.
After being kicked out of the military, Files joined the “outfit” in Chicago, becoming a right-hand man to Mafia chief Charles “Chuckie” Nicoletti, a hitman for Chicago mob boss Sam Giancana.
Files said he also had a now-dead CIA handler.
Files, who is serving time for being an accessory to a mob murder, claims that CIA men felt betrayed over the Bay of Pigs fiasco and feared Kennedy was going to shut the agency down because it was out of control.
They called in mobsters to carry out the killing in Dallas, Texas, he said.
