Dr. Larry Nassar

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.
