HARRISBURG, Pa. (AP) — A former Penn State vice president wants a judge to throw out charges he lied to a grand jury investigating former football assistant coach Jerry Sandusky and didn't properly report suspected child abuse.

Gary Schultz filed the motions Tuesday. In court records first obtained by The Associated Press, he says his statements to a grand jury that the allegations were "not that serious" and that it wasn't clear a crime occurred are opinions that can't be proved false.

He's joining a motion filed Monday by co-defendant Tim Curley challenging the failure-to-report charge on the grounds the law was different in 2002, when they fielded a report about Sandusky being in the showers with a young boy.

The attorney general's office says it hasn't received the filings but will review them when it has.

Sandusky denies molesting boys.
