The public is getting a look at thousands of secret government files related to former U.S. President John F. Kennedy's assassination, but hundreds of other documents will remain under wraps for now.

The U.S. government was required by Thursday to release the final batch of files related to Kennedy's assassination in Dallas on November 22, 1963. But U.S. President Donald Trump delayed the release of some of the files, citing security concerns.
"As long as the government is withholding documents like these, it's going to fuel suspicion that there is a smoking gun out there about the Kennedy assassination," said Patrick Maney, a presidential historian at Boston College.
Here's what to expect.
How many files are there and how can I see them?
The last batch of assassination files included more than 3,100 documents — comprising hundreds of thousands of pages — that have never been seen by the public. About 30,000 documents were released previously with redactions. The National Archives released more than 2,800 documents on its website Thursday evening. But Trump delayed the release of the remaining files after last-minute appeals from the CIA and FBI.
Trump cited "potentially irreversible harm" to national security if he were to allow all the records out now and placed those files under a six-month review. Officials say Trump will impress upon federal agencies that JFK files should stay secret after the six-month review "only in the rarest cases."
Why are they becoming public now?
Former U.S. President George H.W. Bush signed a law on October 26, 1992, requiring that all documents related to the assassination be released within 25 years, unless the president says doing so would harm intelligence, law enforcement, military operations or foreign relations. The push for transparency was driven in part by the uproar in the wake of Oliver Stone's 1991 conspiracy-theory filled film "JFK."
Will there be any bombshells?
The chances are slim, according to the judge who led the independent board that reviewed and released thousands of the assassination documents in the 1990s. The files that were withheld in full were those the Assassination Records Review Board deemed "not believed relevant," Judge John Tunheim of Minnesota told The Associated Press. But Tunheim said it's possible the files contain information the board didn't realize was important two decades ago.
JFK experts believe the files will provide insight into the inner workings of the CIA and FBI. But they stress that it will take weeks to mine the documents for potentially new and interesting information.
What will the files show?
Some of the documents are related to Oswald's mysterious six-day trip to Mexico City right before the assassination, scholars say. Oswald said he was visiting the Cuban and Soviet Union embassies there to get visas, but much about his time there remains unknown.
The to-be-released documents contain details about the arrangements the U.S. entered into with the Mexican government that allowed it to have close surveillance of those and other embassies, Tunheim said. Other files scholars hope will be released in full include an internal CIA document on its Mexico City station, and a report on Oswald's trip from staffers of the House committee that investigated the assassination.
