The 20th Party Congress, actually. I don't know to what extent the content of the speech was known within the USSR at the time (its official existence was only acknowleged in the late 1980s, IIRC).
P&E almost certainly would have seen references to it in American literature though, and might well have been curious enough to read the translation.
