Michigan sports doctor to plead guilty to child pornography charges

A former sports doctor at Michigan State University and USA Gymnastics is taking a step toward resolving one of four criminal cases against him in Michigan.

Dr. Larry Nassar is due in federal court in Grand Rapids Tuesday to plead guilty to child pornography charges. It's separate from sexual assault charges involving women and girls who said they were molested when they sought treatment for injuries.

He's expected to plead guilty to three different charges relating to child pornography. In exchange for pleading guilty to those three charges, prosecutors will not pursue child molestation charges against him.

Nassar was a sports medicine specialist at Michigan State. He also worked for Indianapolis-based USA Gymnastics, which trains Olympians.

Besides the child porn case, Nassar is charged with sexually assaulting nine women or girls in three criminal cases in the Lansing area.

Separately, Nassar is being sued by more than 100 women or girls.
