Four Russians who won gold medals at the Sochi Olympics were on steroids at the time, a whistleblower who previously provided evidence of Russian track and field doping said, according to CBS’ “60 Minutes.”
The “60 Minutes” piece on Russian doping will air Sunday on CBS between 7 and 8 p.m. ET. An excerpt will air on CBS Evening News on Friday between 6:30 and 7 ET.
The whistleblower is Vitaly Stepanov, a former Russian anti-doping official who, along with wife and former Russian 800m runner Yulia Stepanova, provided a 2014 German TV documentary undercover footage and evidence of Russian track and field doping.
