President Donald Trump announced Saturday, with a tweet, that he would allow the classified documents related to the assassination of John F. Kennedy to be released "subject to the receipt of further information".
Congress mandated in 1992 that all assassination documents be released within 25 years, but Trump has the power to block them on the grounds that making them public would harm intelligence or military operations, law enforcement or foreign relations.
The remaining files include more than 3,000 documents never seen by the public, as well as more than 30,000 files that were previously released with redactions.
Trump himself is no stranger to the controversies and conspiracy theories that have long swirled around the assassination of the 35th president.
The Washington Post reported earlier Saturday that an unidentified National Security Council official said in an interview that some unnamed federal agencies were asking Trump not to release an unknown number of the files because they involved sources and methods used by the agencies.
The anticipated release has had scholars and armchair detectives buzzing. Instead of squashing conspiracy theories, the release of the last files may just exacerbate them.
However, the assassination has since been the object of feverish speculation to this day. Lee Harvey Oswald was convicted of his murder, with the Warren Commission appointed by Kennedy's successor, Lyndon Johnson, finding he acted alone.
He said the release would be subject "to the receipt of further information".
The thousands of documents are set for release by the National Archives on October 26, but it has been unclear if President Trump would block their release on the basis of national security concerns. "It sheds very bad light on the deep state", he said.
The former chairman of the Assassination Records Review Board told Dallas News, "I don't think there are big revelations".
Rex Bradford, president of the Mary Ferrell Foundation, which publishes assassination records, was quoted by the CBS News as saying that Kennedy experts also hope to see the full report on Oswald's trip to Mexico City from staffers of the House committee that investigated the assassination.
