A whistleblower who exposed doping by Russian athletes who competed in the 2014 Winter Olympics and who was hit with a libel lawsuit is punching back through the courts with claims of his own, accusing the Russian billionaire who owns the Brooklyn Nets National Basketball Association franchise of trying to silence him.  

Dr. Grigory Rodchenkov—who was featured in the Oscar-winning documentary “Icarus“—ran Russia’s laboratory for assuring compliance with World Anti-Doping Agency regulations. Rodchenkov said in court papers filed Monday that the lab was actually used to further a state-sponsored conspiracy to load up Russian athletes participating in the 2014 Winter Olympics games in Sochi, Russia, with performance-enhancing drugs.
