He is accused of molesting young girls who he was treating for injuries.
The doctor also faces a string of lawsuits filed by alleged victims.Last week, an Ingham County judge ordered Nassar to stand trial on the sex assault charges, while he separately faces child pornography charges in federal court.
Nassar and Michigan State are also being sued by dozens of women and girls, while a motion filed Friday in federal court seeks to add 23 more plaintiffs.
Indianapolis-based USA Gymnastics is a defendant in some of the lawsuits.

A plea bargain means that Nassar will not be prosecuted on charges of sexual exploitation and attempted sexual exploitation of children, Click on Detroit reports.
He could face up to 20 years in prison after admitting possession of child pornography between 2003 and 2016.
One of his victims had described the sexual abuse she suffered aged 11 at the hands of Nassar, during a 2012 appointment for a heel injury.
She told the court, at an earlier hearing, how the Michigan sports doctor has asked her father to leave the room before he penetrated her with his fingers. At the time, she hadn’t said anything because she was embarrassed and thought it might be a legitimate procedure.
‘I remember lots of pain,’ the 16-year-old, identified as victim A, told a judge.

The case involves seven women or girls, although dozens of others have also accused him of sexually assaulting them and are suing him in federal court.
Nassar was a doctor at Michigan State University and at USA Gymnastics, which trains Olympians and other elite athletes. He’s accused of molesting the women and girls with his hands but denies wrongdoing.
The 16-year-old, who was abused while seeking treatment for an injured heel, described the doctor as being ‘quite sweaty’ during the alleged assault and ‘into it’ but did not have an erection, according to MLive.
She said he also touched her labia majora, clitoris and the inside of her vagina while rubbing the thigh of the leg that had a painful heel.
She said she came forward after reading other gymnasts’ accounts last year in an Indianapolis Star story about Nassar.
‘Everything in my mind clicked, and everything crystallized, of him abusing girls,’ she told the outlet.

The subsequent months have been tough.
‘There have been lots of nights where I just cried and cried,’ she said.
Another 16-year-old girl had testified on May 12 that she went to Nassar to help her back, but she said he never indicated that he would be touching her private areas with ungloved hands.
Another alleged victim, 18, said that while the doctor went inside of her vagina with his fingers he peppered her with questions such as ‘Does this feel better? Does this take your pain away?’
She also said he opened her rectum with tape but didn’t touch it, and told her he did this for all the Olympians. She said she’s having a hard time concentrating on her senior year in high school because of the trauma.

Nassar is facing four separate criminal cases, including one alleging he had child pornography.

Three former Team USA gymnasts, including an Olympic medalist, previously detailed claims of sexual abuse allegedly at the hands of the same doctor.
Sydney Olympics bronze medalist Jamie Dantzscher, US national rhythmic gymnastics champion Jessica Howard and US team gymnast Jeanette Antolin revealed the allegations of abuse by Dr Larry Nassar on 60 Minutes in February.
‘He would put his fingers inside of me and move my leg around,’ Dantzscher told the program. ‘He would tell me I was going to feel a pop and that that would put my hips back and help my back pain.
‘It happened all the way to the Olympics in Sydney, until I was 18.’

Dantzscher filed a lawsuit against Nassar in California last September as ‘Jane Doe’, but gave up her anonymity for the 60 Minutes interview.
Howard, who was the national rhythmic gymnasts champion from 1999 through 2001, said she had a severe hip problem when she was 15 and USA Gymnastics suggested she go to a camp called Karolyi Ranch to work with Nassar.
‘He started massaging me. And he had asked me not to wear any underwear. And then he just continued to go into more and more intimate places,’ she said.

Nassar has denied the charges, saying he conducted only legitimate medical procedures.
Antolin, a US team member from 1995 to 2000, said she only realized last year what she thought was treatment had been abuse.
‘It was like a light bulb went off,’ Antolin said. ‘I trusted this man. Just knowing how vulnerable I was as a kid, to not know something like that would be inappropriate, just ruined me.
‘I remember being uncomfortable because of the area. But in my mind, I was like: “If this helps, I’ll do anything”.’
California attorney John Manly is representing more than 40 women in a lawsuit against USA Gymnastics for failing to protect his clients.
He says has accused the US sports federation of falling asleep at the wheel, Nassar may have abused hundreds of girls over more than two decades, while spots authorities were not pay attention.
‘This is somebody who is a serial predator. But the story here is that no one was watching to protect these girls, and they (USA Gymnastics and the Karolyis) put medals and money first.’
