WADA commission head Richard McClaren commented on the situation regarding the massive use of doping by Russian athletes.

In his opinion, the informant of this organization Grigory Rodchenkov has all the evidence and credible documents to prove the involvement of Russians in the banned drugs.

"Rodchenkov and I met three times. Each time the series of interviews lasted many days. Sometimes we worked for 12 or more hours a day. Their names are confidential. But I will say that among them were athletes, coaches and officials.

There are methods for examining electronic data that allow you to determine when a file was created. Of course, we checked the "Duchess letter" - it was created exactly when Rodchenkov spoke about this. Examination of cans with samples also confirms his words. This is an original and authentic document. In my opinion, a collective sanction should be applied. What exactly is a very difficult question. Thank God, it's not for me to decide, but the IOC. Sanctions should apply not only to athletes who have been convicted of violating the rules at the Games in Sochi, "- quotes the words of McLaren Sport-Express.

Recall that due to the use of doping, the International Olympic Committee has already taken 11 medals from Russia. As a consequence, the host of the 2014 Olympics fell in the unofficial medal standings in the 3rd place.
