Robert White, who was the treasurer for Petters Company Incorporated, continues his testimony today in the federal fraud trial of Tom Petters. White testified yesterday about his role in the $3.5 billion Ponzi scheme that Petters is accused of running. Investors thought their money was used to buy and sell consumer electronics at a fat profit. But the government says the goods never existed. MPR's Cathy Wurzer spoke with Minnesota Public Radio reporter Marty Moylan, who's been following the trial.
