Doping in Russian sports is a significant issue. Russia has had the most (35) Olympic medals stripped for doping violations – nearly triple the number of the second country. From 2011 to 2015, more than a thousand Russian competitors in various sports, including summer, winter, and Paralympic sports, benefited from a cover-up.
Media attention began growing in December 2014 when German broadcaster ARD reported on state-sponsored doping in Russia, comparing it to doping in East Germany. In November 2015, the World Anti-Doping Agency (WADA) published a report and the International Association of Athletics Federations (IAAF) suspended Russia indefinitely from world track and field events. The United Kingdom Anti-Doping agency later assisted WADA with testing in Russia. In June 2016, they reported that they were unable to fully carry out their work and noted intimidation by armed Federal Security Service (FSB) agents. After a Russian former lab director made allegations about the 2014 Winter Olympics in Sochi, WADA commissioned an independent investigation led by Richard McLaren. McLaren's investigation found corroborating evidence, concluding in a report published in July 2016 that the Ministry of Sport and the FSB had operated a "state-directed failsafe system" using a "disappearing positive [test] methodology" (DPM) from "at least late 2011 to August 2015".
In response to these findings, WADA announced that RUSADA should be regarded as non-compliant with respect to the World Anti-Doping Code and recommended that Russia be banned from competing at the 2016 Summer Olympics. The International Olympic Commission (IOC) rejected that recommendation, stating that the IOC and each sport's international federation would make decisions on each athlete's individual basis. On 4 August 2016, one day prior to the opening ceremony, 270 athletes were cleared for competition, while 167 were removed because of doping. In contrast to the IOC, the International Paralympic Committee voted unanimously to ban the entire Russian team from the 2016 Summer Paralympics, having found evidence that the DPM was also in operation at the 2014 Winter Paralympics.
