Trump told reporters Monday that his administration will be releasing 80,000 files, though it’s not clear how many of those are among the millions of pages of records that have already been made public.

“We have a tremendous amount of paper. You’ve got a lot of reading,” Trump said while at the John F. Kennedy Center for the Performing Arts in Washington.

He also said he doesn’t believe anything will be redacted from the files. “I said, ‘Just don’t redact. You can’t redact,’” he said.

Many who have studied what’s been released so far by the government say the public shouldn’t anticipate any earth-shattering revelations from the newly released documents, but there is still intense interest in details related to the assassination and the events surrounding it.

Here are some things to know:

Trump’s order

Shortly after he was sworn into office, Trump ordered the release of the remaining classified files related to the assassination, which has spawned countless conspiracy theories.

He directed the national intelligence director and attorney general to develop a plan to release the records. The order also aimed to declassify the remaining federal records related to the 1968 assassinations of Sen. Robert F. Kennedy and the Rev. Martin Luther King Jr.

After signing the order, Trump handed the pen to an aide and directed that it be given to Robert F. Kennedy Jr., the Trump administration’s top health official. He’s the nephew of John F. Kennedy and son of Robert F. Kennedy. The younger Kennedy, whose anti-vaccine activism has alienated him from much of his family, has said he isn’t convinced that a lone gunman was solely responsible for his uncle’s assassination.

Nov. 22, 1963

When Air Force One carrying JFK and first lady Jacqueline Kennedy touched down in Dallas, they were greeted by a clear sky and enthusiastic crowds. With a reelection campaign on the horizon the next year, they went to Texas for a political fence-mending trip.

But as the motorcade was finishing its parade route downtown, shots rang out from the Texas School Book Depository building. Police arrested 24-year-old Lee Harvey Oswald, who had positioned himself from a sniper’s perch on the sixth floor. Two days later, nightclub owner Jack Ruby fatally shot Oswald during a jail transfer.

A year after the assassination, the Warren Commission, which President Lyndon B. Johnson established to investigate, concluded that Oswald acted alone and that there was no evidence of a conspiracy. But that didn’t quell a web of alternative theories over the decades.

The JFK files

In the early 1990s, the federal government mandated that all assassination-related documents be housed in a single collection in the National Archives and Records Administration. The collection of over 5 million pages of records was required to be opened by 2017, barring any exemptions designated by the president.

Trump, who took office for his first term in 2017, had said that he would allow the release of all of the remaining records but ended up holding some back because of what he called the potential harm to national security. And while files continued to be released during President Joe Biden’s administration, some remain unseen.

Researchers have estimated that 3,000 files or so haven’t been released, either in whole or in part.

And last month, the FBI said that it had discovered about 2,400 new records related to the assassination. The agency said then that it was working to transfer the records to the National Archives to be included in the declassification process.

There are still some documents in the JFK collection that researchers don’t believe the president will be able to release. Around 500 documents, including tax returns, weren’t subject to the 2017 disclosure requirement.

What’s been learned

Some of the documents already released have offered details on the way intelligence services operated at the time, including CIA cables and memos discussing visits by Oswald to the Soviet and Cuban embassies during a trip to Mexico City just weeks before the assassination. The former Marine had previously defected to the Soviet Union before returning home to Texas.

One CIA memo describes how Oswald phoned the Soviet embassy while in Mexico City to ask for a visa to visit the Soviet Union. He also visited the Cuban embassy, apparently interested in a travel visa that would permit him to visit Cuba and wait there for a Soviet visa. On Oct. 3, more than a month before the assassination, he drove back into the United States through a crossing point at the Texas border.

Another memo, dated the day after Kennedy’s assassination, says that according to an intercepted phone call in Mexico City, Oswald communicated with a KGB officer while at the Soviet embassy that September.

The releases have also contributed to the understanding of that time period during the Cold War, researchers said.
