The sentencing hearing for Nassar - which entered a sixth day Tuesday and likely will stretch into Wednesday, as more than 150 girls and women have come forward requesting to read victim impact statements - has not produced new evidence of inaction by USA Gymnastics that permitted Nassar to assault children. The hearing has produced a series of statements from Olympic gymnasts, however - including Aly Raisman - who have asserted the Olympic sports organization enabled Nassar's abuse, and demanded an independent investigation of USA Gymnastics' culpability for Nassar's crimes. Last year, USA Gymnastics commissioned a review of its sex abuse prevention policies, led by a former federal prosecutor, but the review avoided assessing blame for Nassar's crimes, which are the subject of lawsuits against USA Gymnastics and Michigan State filed by more than 130 girls and women who've asserted abuse by Nassar.
