Dr. Larry Nassar

A plea deal could be in the works for a former doctor at Michigan State University and USA Gymnastics charged in federal court with obtaining and possessing child pornography. Documents obtained by The Detroit News and the Lansing State Journal show a guilty plea has been signed by 53-year-old Dr. Larry Nassar. A formal plea agreement hasn't been filed with the court. 

An outspoken former gymnast is expected to testify at a key hearing in a sexual assault case against a Michigan sports doctor. Dr. Larry Nassar is appearing in court near Lansing, Michigan, on Friday for a hearing that will determine if there's enough evidence to send him to trial. He's charged with sexually assaulting seven young gymnasts whom he was treating for a variety of injuries at his Michigan State University clinic. 

Records show a Michigan State University doctor resigned in January after learning the school was considering her termination because she didn't disclose that USA Gymnastics was investigating Dr. Larry Nassar.

The Lansing State Journal reports that documents obtained from Brooke Lemmen's personnel file through the Freedom of Information Act reveal she also removed patient records at Nassar's request.

Nassar was a Michigan State and USA Gymnastics sports doctor.
