On Thursday (Jan. 23), President Trump signed an executive order to release thousands of classified government documents, including the assassination of John F. Kennedy, his brother Robert F. Kennedy, and Dr. Martin Luther King Jr.

There’s always the possibility that something would slip through that would be the tiny tip of a much larger iceberg that would be revealing,” said Larry J. Sabato, director of the University of Virginia Center for Politics.

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.
