(CNN) The issue of doping reared its head at Tokyo 2020 on Friday as the Russian Olympic Committee (ROC) hit back at comments from American swimmer Ryan Murphy which questioned whether Evgeny Rylov's 200m backstroke gold medal was "100% clean."

The International Testing Agency (ITA) told CNN on Friday that it has so far collected over 3,000 samples from over 2,000 athletes as part of Tokyo 2020's anti-doping program. Those sanctions are still in place for the widespread use of a state sponsored doping program which was uncovered in 2016. I don't know if it was 100% clean and that's because of things that have happened over the past."
