Trump declassifies JFK, RFK, Martin Luther King Jr. assassination files

US President Donald Trump signed an executive order Thursday declassifying files on the 1960s assassinations of president John F. Kennedy, his brother Robert F. Kennedy and civil rights leader Martin Luther King Jr.

"A lot of people have been waiting for this for years, for decades," Trump told reporters as he signed the order in the Oval Office of the White House. "Everything will be revealed."

After signing the order, Trump passed the pen he used to an aide, saying "Give that to RFK Jr," the president's nominee to become secretary of the Department of Health and Human Services.

The National Archives has released tens of thousands of records in recent years related to the November 22, 1963 assassination of president Kennedy but held thousands back, citing national security concerns.

It said at the time of the latest release, in December 2022, that 97 percent of the Kennedy records -- which total approximately five million pages -- had now been made public.

The Warren Commission that investigated the shooting of the charismatic 46-year-old president determined that it was carried out by a former Marine sharpshooter, Lee Harvey Oswald, acting alone.

That formal conclusion has done little, however, to quell speculation that a more sinister plot was behind Kennedy's murder in Dallas, Texas, and the slow release of the government files has added fuel to various conspiracy theories.

President Joe Biden said at the time of the December 2022 release that a "limited" number of documents would continue to be held back at the request of unspecified "agencies."

Previous requests to withhold documents have come from the Central Intelligence Agency and the Federal Bureau of Investigation.

Thousands of Kennedy assassination-related documents from the National Archives were released during Trump's first term in office, but he also held some back on national security grounds.

- Conspiracy theories -

Kennedy scholars have said the documents still held by the archives are unlikely to contain any bombshell revelations or put to rest the rampant conspiracy theories about the assassination of the 35th US president.

Oswald was shot to death two days after killing Kennedy by a nightclub owner, Jack Ruby, as he was being transferred from the city jail.

Hundreds of books and movies such as the 1991 Oliver Stone film "JFK" have fueled the conspiracy industry, pointing the finger at Cold War rivals the Soviet Union or Cuba, the Mafia and even Kennedy's vice president, Lyndon Johnson.

President Kennedy's younger brother, Robert, a former attorney general, was assassinated in June 1968 while campaigning for the Democratic presidential nomination.

Sirhan Sirhan, a Palestinian-born Jordanian, was convicted of his murder and is serving a life sentence in a prison in California.

Martin Luther King Jr was assassinated in April 1968 in Memphis, Tennessee.

James Earl Ray was convicted of the murder and died in prison in 1998 but King's children have expressed doubts in the past that Ray was the assassin.
