The chairman, vice chairman and treasurer of USA Gymnastics resigned Monday, heeding calls from the U.S. Olympic Committee and angered gymnasts who say the organization did nothing to protect them after they were abused by former team doctor Larry Nassar.

Paul Parilla, Jay Binder and Bitsy Kelley announced they were stepping down as testimony in Nassar’s sentencing hearing in Michigan moved into its second week.

A number of Olympians have been among those testifying. Many have also sued the USOC and USA Gymnastics and called for the sports leaders to leave their jobs.

USA Gymnastics CEO Steve Penny was forced out last year.

USOC CEO Scott Blackmun met with Parilla earlier this month and asked for his resignation.
