President Trump said officials planned to disclose a trove of classified government files on Tuesday about the assassination of President John F. Kennedy, and he suggested there would be no redactions this time — in contrast to releases during his previous administration.

The National Archives and other agencies have provided no details or a timeline for the release of the files, however, and it was unclear if they would be disclosed all at once, or in batches over the coming days or weeks. Hundreds of thousands of assassination documents have already been revealed under a 1992 law.

During a visit to the John F. Kennedy Center for the Performing Arts on Monday, Mr. Trump said the new release would total about 80,000 pages. He did not provide additional details on what the files would include, but he has long promised to release the unredacted documents.

“You got a lot of reading,” he told reporters at the Kennedy Center, the cultural and political institution that he took over nearly five weeks ago, installing himself as chairman. “I don’t believe we’re going to redact anything.”

Days after starting his second term in the White House, Mr. Trump signed an executive order mandating the release of all government records related to the assassinations of Kennedy; Kennedy’s brother, Senator Robert F. Kennedy; and the Rev. Dr. Martin Luther King Jr.

President Kennedy’s assassination, in particular, has long fueled conspiracy theories, including some that Mr. Trump himself has indulged.
