Russian doping whistleblower Grigory Rodchenkov taken at an undisclosed location on Monday Aug. 3, 2020. Rodchenkov has spoken to The Associated Press from his hiding in the United States. Revealing his current identity is still too risky for the chemist turned whistleblower, even in a video interview from an undisclosed location. Rodchenkov says he has "physical threats to be assassinated." Rodchenkov was the brains behind the Duchess cocktail of anabolic steroids and cover-up that was turned Russia into a medal machine at the home Olympics in Sochi in 2014, topping the standings with 13 gold medals.
