Aaron Schock has kept the lowest profile this side of Steve Bartman. The former Congressman's whereabouts are a mystery after his recent resignation. An attorney for a campaign donor suing the Peoria Republican has told a federal judge he can't track down Schock. So far process servers for a political donor suing to get his money back have been unable to serve the lawsuit. A Peoria address for Schock is said to be vacant. There's no comment from a Schock spokesman.
