Banker Who Blew Whistle Over Tax Cheats Seeks Pardon

Bradley Birkenfeld, once a UBS AG banker who handled a $200 million investment for a billionaire client, now makes 12 cents an hour mopping floors at the federal prison in Minersville, Pennsylvania. He told U.S. authorities how UBS bankers came to the U.S. to woo rich Americans, managed $20 billion of their assets, and helped them cheat the Internal Revenue Service.
