I think it would be worth contacting his people but he doesn't seem that serious (about online poker) from the article. It sounds like he just wants to flex his fame and meet the greats don't we all lol. Regardless he is synonymous with America and a symbol to all Americans right now and I do feel if he were to openly endorse online poker it would certainly fall on open minds and ears. As I recall on his personal website there is a way to contact his media people this may or may not be current information
