The JFK files: Here's what's happened since their original planned release

With the expected release of the remaining JFK assassination files following President Donald Trump's executive order, here is a look back on the documents' original declassification timeline.

Trump had initially promised to release the last batch of documents during his first term, but such efforts ultimately dissipated. Trump blocked the release of hundreds of records on the assassination following several CIA and FBI appeals.

"I have no choice," Trump said in a memo, where he cited "potentially irreversible harm" to national security if he allowed the records to be released. Trump said at the time the potential harm to U.S. national security, law enforcement or foreign affairs is "of such gravity that it outweighs the public interest in immediate disclosure."

Former President Joe Biden later released another batch of documents in 2021, as well as in 2022 and 2023. The Biden White House announced in July 2023 that the National Archives and the Records Administration had concluded its review of the JFK documents, making 99% of the material publicly available. 

"I have now determined that the continued redaction and withholding of information from records pertaining to the assassination of President John F. Kennedy is not consistent with the public interest and the release of these records is long overdue," Trump's Thursday order states.

JFK's grandson, Jack Schlossberg, also reacted to the declassification news, writing on X that the move was "using JFK as a political prop, when he’s not here to punch back."

"There’s nothing heroic about it," Schlossberg wrote.
