Larry Nassar, the former team doctor for USA Gymnastics and Michigan State University, is back in court Friday for his third sentencing hearing in as many months on charges of criminal sexual misconduct.

At least 65 accusers are expected to testify against him over days of testimony, which began Wednesday in Michigan’s Eaton County Circuit Court. Accusers say his abuse spanned more than two decades.

In January, Nassar was sentenced to between 40 and 175 years in prison.
