'Teen skater failing doping test shows vulnerability of young athletes'

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 (above) helped the Russian Olympic Committee (ROC) to a team gold in Beijing after landing the first quadruple jump in the Games competition on Monday.
