Russian officials have admitted to Rebecca R. Ruiz of the New York Times that they were involved with doping during "the entire Olympic movement," including the 2014 Winter Games in Sochi, Russia.
In an investigation carried out by Richard McLaren, who was appointed to do so by the World Anti-Doping Agency, it was found that illegal substances were supplied to Russian athletes in what was described by Ruiz as "one of the biggest conspiracies in sports history," which included "years' worth of cheating schemes."
McLaren had published his findings earlier in December, via Ruiz, where he stated that over 1,000 athletes across 30 sports were involved in the doping program.
