USA Gymnastics Chief Operating Officer Ron Galimore has resigned, according to the organization.
Galimore, a 1980 U.S. Olympian, had been in the role since 2011 and with USA Gymnastics since 1994. He was the highest-ranking official left at USA Gymnastics who was employed while Larry Nassar committed sexual-abuse crimes against gymnasts.
Other top officials, including president and CEO Steve Penny, previously resigned or were forced out.
In May, the Indianapolis Star reported that Galimore was one of the USA Gymnastics officials who covered up why Nassar was absent from events in 2015, after gymnasts first reported that Nassar abused them.
