The Russian government is still intent on attacking the credibility of the man who exposed the country’s elaborate doping program, and Brooklyn Nets owner Mikhail Prokhorov is reportedly one of the people who is providing financial backing. According to a report from Tariq Panja of the New York Times, Prokhorov is helping fund a defamation lawsuit against Dr. Grigory Rodchenkov, whose uncovering of Russia’s state-sponsored doping program resulted in the country being banned from the 2018 Winter Olympics in PyeongChang. The suit has been filed by three Russian biathletes — Olga Zaytseva, Yana Romanova and Olga Vilukhina — who are seeking $10 million in damages after they had their silver medals from the 2014 Sochi Olympics stripped. Prokhorov was the leader of the Russian biathlon federation in Sochi, which likely explains his interest in the lawsuit. Panja notes that the suit has little chance of succeeding, and Rodchenkov’s attorney says he is not concerned about it.
