In the context of a Republican letter to Iran, Limbaugh said that Kennedy sent a similar letter to Andropov in the 1980s that apologized for Reagan and begged the Soviets not to overreact. There is no evidence there ever was a letter from Kennedy. Limbaugh’s statement rests on a 1983 KGB memo that said there was a verbal overture from a friend of Kennedy’s to meet with Andropov. Whether the memo was accurate or a KGB invention is deeply contested. We have a firm denial from the man who allegedly made the overture, and a Soviet archive researcher told us that memos of this sort are not always reliable. So Limbaugh was wrong about the letter, and spoke with great certainty about an event when its authenticity is very much in question.
Overall, we rate the claim False.
