An order to declassify documents related to the assassinations of John Fitzgerald Kennedy, his brother Robert Kennedy, and Martin Luther King was signed Thursday by Donald Trump.

It was one of Trump’s campaign promises that he implemented by signing an executive order as part of a “storm” of executive orders in the early days of his presidency.

They are three assassinations, the 1963 assassination of President John F. Kennedy, and the 1968 assassinations of Robert Kennedy and King that shocked the US.

The first one in particular created endless conspiracy theories about who, how and why they planned the assassination of a popular president.

On Wednesday, Trump had said he had intended to go ahead with declassification during his first term, but did not do so because he was asked to do it as a favor by then-Secretary of State Mike Pompeo – whose rights he now revoked.
