Newly released documents from the CIA show that the spy agency intercepted a phone call from Lee Harvey Oswald, John F. Kennedy’s assassin, to the KGB department in Moscow that handled “sabotage and assassinations.”

Just over a month before Oswald assassinated Kennedy on November 22, 1963, the CIA intercepted a phone call he made to Valeriy Vladimirovich Kostikov.

The CIA identifies Kostikov as an officer in the KGB’s 13th department, which is “responsible for sabotage and assassination.”

Oswald asked Kostikov whether there was “anything new concerning the telegram to Washington,” and Kostikov told him there was not.

That telegram, though not explained in the CIA document, most likely had something to do with Oswald’s 1959 attempt to defect to the Soviet Union by traveling to Moscow. The Soviets denied his bid for citizenship but allowed him to stay in the country for a few years.

The CIA document does not conclude that Oswald acted against Kennedy on Russian instructions or with help from the KGB.

Peter Savodnik, the author of “The Interloper: Lee Harvey Oswald Inside the Soviet Union,” told The Atlantic in 2013 that Oswald, who joined the Marine Corps at 17, had moved with his mother 20 times during his childhood and most likely sought to live in Moscow to gain some feeling of permanence.

Savodnik maintains that instead of grooming Oswald as a potential agent against Moscow’s rivals in Washington, Soviet authorities sent him to live hundreds of miles away in Minsk, Belarus, because it was “sleepy and boring and quiet.”
