The prestige conferred on Nassar by his volunteer position at the Olympics, by both the parents of gymnasts and clinical sports medicine in general, is hard to overstate and hard, from the outside, to understand....

MSU Title IX investigator ... launched her own investigation. She interviewed three osteopathic physicians and one athletic trainer. All four found Nassar’s conduct to be medically appropriate.
