US President Donald Trump has hinted at the release of the final batch of the files detailing the probe into the 1963 assassination of former US President John F. Kennedy. According to the president’s recent tweet, the files are scheduled to be released on Thursday.

The files had been approved for release since a Congress law in 1992, but has since been delayed.

“The long anticipated release of the #JFKFiles will take place tomorrow. So interesting!”, Mr Trump wrote.

The files represent just one per cent of all the files in the total investigation, the other portion of the files have been released to the public, with some containing redacted materials.

It’s not clear what the files might contain, but some have speculated that there could be information detailing the methods and sources used by the CIA or FBI in Mexico City in the months before the assassination, after Kennedy’s assassin, Lee Harvey Oswald, travelled to Mexico City in September of 1963, just two months before Kennedy was killed.

The assassination of the 35th American president sparked one of the greatest controversies in history, with many unwilling to accept that Oswald could have acted alone and fired three shots within eight seconds, killing Kennedy at Dealey Plaza in Dallas on Nov. 22, 1963.

A Senate committee later found that the assassination may have been conducted as the result of a rogue intelligence agency staffer as a part of a conspiracy, while others believed that the Cuban government had plenty of reason to attempt to take Kennedy’s life, owing to repeated attempts by the US to kill former Cuban leader Fidel Castro.

According to New York Times, historians and conspiracy investigators are eager to see what the documents may yet reveal about Lee Harvey Oswald and any ties he may have had to the Cubans, Soviets, C.I.A., F.B.I. or mafia, while some hope for a better understanding of Oswald’s trip to Mexico City, where he visited the Cuban Consulate in the weeks before the assassination.

However, some specialists on the killing including Gerald Poshner, author of “Case Closed,” the 1993 book that concluded that Oswald indeed killed Kennedy on his own, warned against expecting any stunning revelation.

“I don’t think it will turn the case on its head,” said Gerald Posner

“We’re not going to find some secret memo from J. Edgar Hoover drawing out the escape path for Lee Harvey Oswald. The public expectations are very high — they’ve heard about secret files, they know they’ve been locked up for all these years. The average person may think there’s a bombshell in there”, he said.
