Sandusky, a former Penn State assistant football coach, is already being prosecuted by the Pennsylvania state Attorney General's Office over allegations that he sexually abused young boys over a 15-year period. A Penn State spokeswoman said Thursday that the university received a subpoena from the U.S. Attorney for the Middle District of Pennsylvania requesting information about Sandusky and his charity. The U.S. Attorney's office also asked for information about former president Graham Spanier, and Tim Curley and Gary Schultz, two former school officials charged with perjury and failure to report a crime. Prosecutors have alleged that Sandusky met his accusers through the Second Mile, the youth charity he founded. Sandusky has also been accused of taking one of the alleged victims across state lines to bowl games in Texas and Florida, an issue that federal authorities could be looking into. Joe Amendola, Sandusky's attorney, said he has no comment on the matter. Sandusky, who faces more than 50 counts of child sex abuse, is currently under house arrest as he awaits trial. Last week, Penn State said it has incurred nearly $3.2 million in combined legal, consultant, and public relation fees pertaining to the Sandusky scandal. Roughly $500,000 has been spent on university legal defense services, the university said. CNN contributor Sara Ganim contributed to this report.
