Lilly King finger wagged Russian swimmer Yulia Efimova and beat her for the gold medal in the 100m breaststroke for America. Efimova was only allowed to compete in the Olympics at the last moment. She was banned for a positive steroid test in 2014 and was caught up in the Meldonium scandal in 2016.
A fact that was excised from the NBC narrative: Efimova was popped for doping twice, while living and training in Los Angeles.
While her actual life presumably involves a lot of grueling, repetitive time at the gym and in the pool, her Instagram presence details a lot of fun time spent at the beach.
