He was sentenced in January and February in two separate hearings to 40 to 175 years and 40 to 125 years in prison.Around 200 women, including Olympic gold medal-winning gymnasts Aly Raisman and Jordyn Wieber, gave courtroom statements at the sentencing hearings about Nassar's abuse, leading to the resignation of the USA Gymnastics' board.
