Yes, he donated some $$$ to the Republican Party and apparently his name slipped through the cracks (maybe donated and/or invited as "Eric Wright" - I think that was his real name) when some White House invites went out.
I have a feeling that it was one of those, "I bet if I donate enough money they'll even invite ME to the White House" kinds of things that he, Ice Cube, Dr Dre, etc all had a good chuckle over and that made William Bennett and Tipper pass out.
