Greek Olympic pole vault champion Katerina Stefanidi has slammed US Anti-Doping Agency (USADA) chief Travis Tygart for his calls to ban all Russian athletes from the 2020 Tokyo Games, telling him to “clean up his own house.”

The 2017 world champion said the US anti-doping watchdog doesn’t have the reputation to talk about clean athletes, taking into account numerous US doping cases that have rocked the sports world.

She also suggested that some American athletes get away with doping offences by using explanations such as eating “steroid-infused meat.”
