Surprise! There's another doping scandal at this year's Winter Olympics. This time, it's (surprise!!) a Russian athlete, bobsledder Nadezhda Sergeeva. The Russian Bobsled Federation -- yes, that is a thing -- confirmed that she tested positive for a banned substance, a heart medication that affects metabolism. What makes this more surprising is two weeks before the Olympics she was seen wearing a sweatshirt that read, " I don't do doping." Well, apparently she does.
