See, this is the kind of response that makes people not trust Politifact. This article delivers a more detailed version of exactly what I said. There's direct evidence indicating Kennedy reached out to the KGB, and indirect evidence it was tied to his political ambitions, but there's no ironclad proof and some people believe the evidence was just a complete fabrication. The "false" rating is based entirely on the specific claim that Kennedy sat down for a meeting with them, which I think you'll find I did not make.
