BEIJING (Reuters) - Rachael Denhollander, the first woman to publicly accuse former USA Gymnastics doctor Larry Nassar of sexual abuse, told Reuters that Russian skating prodigy Kamila Valieva's failed drug test is a reminder of how vulnerable young athletes remain.

The 15-year-old Valieva helped Russian Olympic Committee (ROC) to a team gold in Beijing after landing the first quadruple jump in Games competition on Monday.
