Donald Trump plans to release documents related to the 1963 assassination of President John F Kennedy. The documents are due to be made public this week unless the president decides otherwise.
The Washington Post says the documents are required to be opened by Thursday under a 1992 act, exactly 25 years later. It says only the president is entitled to stop it.
Trump tweeted on Saturday that he will allow the long blocked and classified files to be opened.
Some media report the National Security Council is urging Trump not to release some of the documents. As a result, it is uncertain whether all the documents will be disclosed in their original form.
President Kennedy was assassinated in Dallas, Texas, in 1963. Former marine Lee Harvey Oswald was arrested in connection with the case. The Warren Commission concluded that he acted alone.
