Trump's order is aimed at releasing documents related to the assassinations of the former president, presidential candidate and civil rights leader.

US President Donald Trump ordered the declassification Thursday of the last secret files on the assassination of president John F. Kennedy, a case that still fuels conspiracy theories more than 60 years after his death. But that formal conclusion has done little 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.
