Comey was the United States Attorney for the Southern District of New York, from January 2002 to the time of his confirmation as Deputy Attorney General on December 11, 2003. Among his first tasks was to take over the investigation into President Bill Clinton's controversial pardon of Marc Rich. In November 2002, he led the prosecution of three men involved in one of the largest identity fraud cases in American history. The fraud had lasted two years and resulted in thousands of people across the country collectively losing over $3 million. He also led the indictment of Adelphia Communications founder John Rigas for bank fraud, wire fraud, and securities fraud. Rigas was convicted of the charges in 2004 and in 2005, was sentenced to 15 years in federal prison. Adelphia Corporation was forced to file for bankruptcy after it acknowledged that it took $3. 3 billion in false loans. It was "one of the most elaborate and extensive corporate frauds in United States history".
