JFK Fact Check: Was Lee Harvey Oswald Under CIA Surveillance?

Answering a key question raised by the recent declassification of the CIA file on JFK's accused assassin

Five senior CIA officials who knew about Oswald while JFK was alive (clockwise from upper left): Tom Karamessines, Assistant Deputy Director of Plans; Elizabeth Ann Egerter, CI/SIG file supervisor; Jane Roman, counterintelligence liaison officer; William J. Hood, acting chief of operations in the Western Hemisphere; and John Whitten, chief of the CIA’s Mexico desk.

The JFK Facts report that accused assassin Lee Harvey Oswald was under CIA surveillance from 1959 to 1963 has been challenged by national security reporters Mike Isikoff and Gus Russo.

As evidence, I cited the 194-page dossier on Oswald compiled by the CIA before Nov. 22, 1963. This file, consisting of 43 documents, was maintained and controlled by counterintelligence chief James Angleton, one of three most powerful men in the clandestine service. Last year, I conducted a class in crowdsourcing with 60 students who studied it. We found that at least 30 CIA employees in a dozen different offices received information on Oswald during JFK’s presidency.

The existence of the Oswald file was not disclosed to the Warren Commission. Its contents were not fully declassified until April 2023.

In response, Isikoff and Russo concede Oswald was under CIA mail surveillance while he lived in the Soviet Union, but they claim the CIA only obtained one letter, with the implication the surveillance found nothing of interest. They say that the Cuban and Soviet Embassies in Mexico City, which Oswald visited in September 1963, were under surveillance, but Oswald himself was not. The Oswald file has been known for decades, they insist. “There’s less here than meets the eye,” they claim.

So let’s do some fact-checking.
