The representative of the World Anti-Doping Agency, WADA, said that the organization did not receive documents from the Russian Investigative Committee that refute Grigory Rodchenkov's information about substitutions of doping samples of Russian athletes at the Sochi 2014 Olympics.

"The findings of McLaren's investigation were based on extensive, reliable and confirmed evidence of institutionalized doping in Russia, and WADA remains absolutely confident in these findings," said an employee of the anti-doping agency RIA Novosti..

According to the representative of WADA, the findings of McLaren's investigation were convinced by the agency, therefore RUSADA needs to return to compliance with the norms of the international organization as soon as possible and more efficiently. The official representative of the Investigative Committee of Russia, Svetlana Petrenko, earlier reported that WADA sent documents denying the testimony of informant Grigory Rodchenkov about night-time substitutions of doping samples of Russian athletes at the Sochi Olympics. According to Petrenko, all the samples were delivered to the Sochi laboratory in the afternoon, they were registered and sent to the study for a maximum of two hours.
