The head of the U.S. Olympic Committee, Scott Blackmun, is stepping down amid criticism over his handling of the case of Larry Nassar, the former USA Gymnastics team doctor who was convicted of sexually abusing hundreds of women and girls. Blackmun’s resignation came after The Wall Street Journal reported he and the U.S. Olympic Committee failed to intervene in 2015 when they first heard allegations of Nassar’s sexual abuse—a full year before the crimes were reported publicly by The Indianapolis Star.
