President Trump said he'll declassify any remaining files from John F. Kennedy, Robert F. Kennedy and Martin Luther King Jr.'s assassinations.

Under the order, intelligence officials must present a plan within 15 days for the “full and complete release” of records on the assassination of John F. Kennedy, who was shot to death in Dallas in November 1963.

"For us, the assassination of our father is a deeply personal family loss that we have endured over the last 56 years," said Bernice King and Martin Luther King III.
