President Donald Trump signed an order Thursday related to the declassification of files on the assassinations of former President John F. Kennedy, Robert Kennedy and Martin Luther King Jr. Trump says the attorney general and the director of national intelligence have two weeks to create a plan to release the documents.

During his first term, Trump said he’d release all remaining records on JFK’s assassination, which has fueled conspiracy theories for decades, but he ended up holding some back due to potential harm to national security.
