Last November JFK Facts reported a previously unknown fact: the CIA compiled a 181-page dossier on accused assassin Lee Harvey Oswald before President Kennedy was assassinated on November 22, 1963.

This figure that that has now been fact-checked—and revised upward.

What is the Oswald file?

My interest in the pre-assassination Oswald file was piqued in April 2023. That’s when the last redaction in file was lifted. All of the 42 document in the file had been completely redacted as of 2017. All that remained classified was one name

In April 2023 it was revealed CIA operations officer, Reuben Efron had monitored Oswald’s private correspondence for the first 18 months of JFK’s presidency. At the time Efron reported to counterintelligence chief James Angleton, one of the most powerful men in the CIA.

Even the New York Times took note of this JFK development in July 2023.

JFK Facts original story on the Oswald file yielded at least other two significant findings.

  • A supersecret CIA mole-hunting unit known as the Special Investigations Group (CI/SIG), received 17 reports on Oswald in the four years before JFK was assassinated, including five FBI dispatches in the three months before JFK was killed.

  • At least 35 CIA employees handled reports on Oswald between 1959 and 1963, including a half dozen officers who reported personally to Angleton or deputy director Richard Helms.
