“A congressional official who has been closely monitoring the issue, speaking on condition of anonymity, said Trump had been under pressure from the CIA to block the release of some of the assassination documents on national security grounds, possibly to protect CIA tradecraft and the identity of agency informants who might still be alive.

The 1992 law, the JFK Assassination Records Collection Act, was passed by Congress in response to the furor created by Oliver Stone’s conspiracy-laden hit film “JFK,” which was released the year before. As a result of the law, millions of pages of documents related to the assassination were made public in the 1990s—but not all.

Stone, author of a book alleging that President Lyndon B. Johnson was the mastermind of JFK’s assassination, has said that he had been told authoritatively that CIA Director Mike Pompeo is urging Trump to block the declassification of some of the agency’s files.”
