The assassination of President John F. Kennedy still looms over American history, and Donald Trump has made it clear that he believes Lee Harvey Oswald was the killer. However, in a recent interview aboard Air Force One, Trump suggested the possibility that Oswald may have had help.

Last week, Trump ordered the release of over 2,000 previously classified documents related to the assassination. Among them were claims from a high-ranking CIA agent, who suggested that the deep state was involved and that Oswald was a “poor shot.” Despite this, Trump wasn’t particularly impressed by the documents, stating that nothing in them was “earth-shattering.”

Though Oswald was arrested and later killed by Jack Ruby, conspiracy theories persist, with some suggesting Oswald was part of a larger plot involving the CIA, Mafia, KGB, or other groups.

Trump believes Oswald acted alone but leaves open the possibility that he was helped. The debate over the assassination continues, and the release of new documents has reignited questions about what truly happened that day in 1963.
