From the Dallas Morning News:
WASHINGTON — President Donald Trump issued an order Thursday keeping some of the most sensitive records from the Kennedy assassination files sealed for another 3-1/2 years, as the National Archives released a final batch under a law meant to force most of the records into the light by last fall.
In 1992, Congress set a 25-year deadline for releasing remaining documents stemming from John F. Kennedy's murder in Dallas on Nov. 22, 1963.
When the deadline arrived — Oct. 26 last year — Trump gave federal agencies a six-month extension to plead the case for keeping selected records sealed, if they could assert a vital national security interest. The FBI and CIA in particular had pressed for more time.
