After days of powerful testimony, former gymnastics doctor Larry Nassar was sentenced to life in prison yesterday.But, as the hearing ended, the judge and a number of women who testified said it is crucial now to focus on what needs to change moving forward.We're going to focus on that tonight with a renowned gymnast, Shannon Miller.She won more Olympic medals than any other U.S. gymnast, and led the team that was dubbed the Magnificent Seven to gold during the 1996 Olympics.Miller wasn't assaulted by Nassar. But she is a leading voice working to reform the sport.I spoke with her earlier today, and we started with her reaction to the testimonies she heard during the sentencing hearing.I think I have just been in a state of shock and sadness, outrage.And to listen to the victim-impact statements, as a mother, as an athlete, as a woman, it is ― it is absolutely heartbreaking.And I take those voices with me each day as I continue to relentlessly focus on agenda-based change. Change has to happen.You have been talking and writing about that. Before we talk about changing the system, though,I want to ask you if you think others besides Larry Nassar should be held accountable,the U.S. Olympic Committee, Michigan State, other institutions?
