I don't really follow show jumping but there is a guy named Kent Farrington from Chicago that was selected.
According to Club Equestrian the Jumping team and Eventing team have been selected? Maybe? I could be totally wrong, I'm new to all of this...
Here's the link but you have to have a Club Equestrian account to sign in:http://www.clubequestrian.com/games/pick8/
Okay, edited to add: This is actually a contest to pick the people who will make
the team. Sorry about that! However, its got some pretty cool bio's on everybody!
