Russia says it supports retesting drug test samples from the 2014 Sochi Olympics after accusations it operated a mass doping program at the games. Grigory Rodchenkov, the former head of the Russian anti-doping laboratory, told the New York Times he switched tainted urine samples for clean ones for athletes allegedly identified by the Russian government as being part of a state doping system. ”It all needs to be retested,” Russian Sports Minister Vitaly Mutko told the state R-Sport news agency on Saturday.
