President Donald Trump fulfilled a campaign promise by releasing thousands of additional files related to the assassination of John F. Kennedy. The documents, totaling 63,400 pages, are being scrutinized by academics and amateur sleuths for insights into the events of Nov. 22, 1963. One document, a CIA memo from 1967, highlighted allegations that the CIA was involved in the assassination. The memo discussed the mysterious death of CIA whistleblower Gary Underhill, who reportedly feared for his life and was found dead in 1964. Despite the attention the memo received, it did not provide new revelations about Underhill's allegations, which were previously discussed in a 1967 interview with district attorney Jim Garrison.
