One focus of the probe appears to be on the World Anti-Doping Agency, which reviewed repeated positive drug tests by elite Chinese swimmers.

The World Anti-Doping Agency acknowledges it knew of doping concerns involving 23 Chinese swimmers before the 2021 Tokyo Games but failed to alert others. Some of those swimmers later won gold medals.

Kamila Valieva helped Russia win gold in team figure skating at the 2022 Beijing Olympics. It wasn't until after the competition that it was learned she'd previously tested positive for doping.

The 15-year-old athlete tested positive in December for trimetazidine, a drug typically prescribed to much older patients suffering from angina and other heart-related conditions.

The International Olympic Committee says it will abide by a decision that 15-year-old Kamila Valieva be allowed to skate in Beijing but if she wins "no medal ceremony will take place."

The usually much-discussed topic hasn't been making headlines during the Tokyo Games as often because of the pandemic. But it's still there.

Critics are outraged, saying the anti-doping agency for the Games is ignoring the actions of the white athlete on the heels of suspending the Black sprinter this month.
