After a January executive order demanded that more files related to the 1963 assassination be declassified, the National Security Division reportedly pulled an all-nighter to get the job done.

President Donald Trump’s administration released thousands of classified documents related to the 1963 assassination of President John F. Kennedy, but researchers say the trove excluded two-thirds of the promised files.
