President-elect Donald Trump said on Sunday he would release classified documents in the coming days related to the assassinations of U.S. President John F. Kennedy, Senator Robert Kennedy and civil rights leader Martin Luther King Jr.

Trump, returning to the White House, vowed to release classified documents on the JFK assassination and others. While he previously released some files, many remain classified due to national security concerns.

Donald Trump has promised to make things real interesting, real fast for America’s hordes of conspiracy theorists—not to mention Hollywood screenwriters and the creators of lucrative true-crime podcasts.
