Mr. Trump is ordering the director of national intelligence and attorney general — neither official has been confirmed yet — to spend the next 15 days coming up with a plan to release the JFK files.

Mr. Trump’s order also will declassify more records on the 1968 assassinations of Dr. Martin Luther King Jr. and former senator and attorney general Robert F. Kennedy. The DNI and attorney general will have 45 days to come up with plans to release the RFK and MLK files.
