I think I recall seeing that the Russian lawyer was escorted while in the U.S. by old Ron (Commie) Dellums who retired from the House after serving the CA 9th District for 27 years. It would be interesting to know why Dellums was selected for this job.
Maybe because Dellums was so willing to follow Cuban orders back in the 80s to vote in ways that would facilitate the construction of Soviet air bases in this hemisphere.
