Garry Kasparov has regular interactions with U.S. chess players, especially juniors, but this bit of conjecture/rumor-mongering by Russian Chess Federation President Leonid Filatov seems based on a misunderstanding of Kasparov's activities in the U.S. Or, perhaps, he's just stirring the pot for some reason. If it turns out to be true, though, I for one would be quite happy about it.
