Graham Spanier filed notice of intention to sue one day before the one-year anniversary of the day on which Freeh released a report that led to Spanier's firing, NBC News reported Friday.
The report claimed Spanier was one of four powerful people at the university "who failed to protect against a child sexual predator harming children for over a decade," NBC News reported Friday.
Freeh's office declined to comment on the potential lawsuit, noting that felony charges were pending against Spanier.
Those charges include lying to a grand jury, obstruction of justice and endangering the welfare of children.
Spanier has repeatedly professed his innocence in interviews during the last year, The (Harrisburg) Patriot-News reported.
He claims Freeh's characterization of him in the report was negligent. Spanier's filing indicated he plans to seek monetary damages from Freeh and his law firm.
