Gregory Rodchenkov, who used to head the Moscow Anti-Doping Laboratory, made a private business out of doping, and when it was discovered, he fled Russia to avoid prosecution.
Rodchenkov was Convicted and Sentenced in Absentia September 28, 2017 by Russian court and a warrant for his arrest has been issued.
Rodchenkov has been given sanctuary and protection in the US because he swears that the Russian Government did it all, not him.

You see, if we Americans won't help Russian Criminals expose doping, who will?
Reminds me Bill Browder and Sergey Magnitsky. They have defrauded investors and cheated on taxes and after got caught Browder went to McCain and the whole story was turned upside down. Then Magnitsky died from alcohol-related health issues but officially ‘tortured to death by Putin’. Also Browder is now somehow a victim and ‘whistleblower’ who ‘exposed’ some sort or ‘corruption’. Which whistle he blows is a question by itself but you don’t hear a lot of details of ‘corruption’ because the story would fall apart in this case.
