Russian whistleblower Vitaliy Stepanov initially met with World Anti-Doping Agency representatives at the 2010 Winter Olympics, and said he had heard of a list of athletes who were "protected" in the leadup to those Games and which RUSADA was told not to test.
On Thursday, Beckie Scott, a Canadian Olympic gold medalist and WADA Athlete Committee chair, spoke at the WADA Executive Board meeting in Montreal and urged the agency to use its influence now. "If there cannot be a guarantee that athletes [at the Olympics] are professionally clean and not involved in doping activity, then they should not be there," she said.
On Sunday evening, 60 Minutes aired a 13-minute interview with Vitaly and Yuliya Stepanov, the whistleblowers who prompted a German documentary on Russia's systematic doping in track and field and WADA's resulting ban on the entire team. Vitaly suggests the corruption extends to Russian Winter Olympians as well, including at least four who achieved gold in Sochi with the help of federal agents.
