President Donald Trump will decide within months — or even weeks – whether to let the public see thousands of long-secret government files about the 1963 assassination of President John F. Kennedy, Politico reported Thursday.

Under a deadline set by a 1992 law, Trump has six months left to decide whether he'll block the release of an estimated 3,600 files related to the assassination still under seal at the National Archives.

Most come from the CIA and FBI, and a number may help resolve lingering questions about whether those agencies missed evidence of a conspiracy in Kennedy's death.

According to Politico, it's "virtually certain" some files will be used to support popular conspiracy theories about Kennedy's murder – but others are likely to undermine them.

The documents were gathered together by a temporary federal agency, the Assassination Records Review Board established under the 1992 law.

Its former chairman, Judge John Tunheim of the Federal District Court in Minnesota, told Politico last month he "wouldn't be surprised if there's something important" in the documents.

But he also said he knew of "no bombshells" in the files when the board agreed to keep them secret two decades ago.

"Today, with a broader understanding of history, certain things may be far more relevant," he told Politico.

The White House is well aware of the deadline, and an unnamed official told Politico the administration is working with the National Archives "to enable a smooth process in anticipation of the October deadline."

Under the 1992 JFK Assassination Records Collection Act, the library of documents about Kennedy's death must be made public in full by Oct. 26 – unless Trump decides otherwise. "It is his decision alone," the outlet reported.

Beyond releasing the never-before-seen JFK files, the Archives is reviewing another 35,000 assassination-related documents, previously released in part, so they can be unsealed in full.
