American swimmer Lilly King explained that she is "not a fan" of Yuliya Efimova after she was seen wagging her finger at the Russian at Rio 2016 on Sunday.
Efimova, 24, was initially banned from the 2016 Games as a result of the International Olympic Committee's decision to prevent any Russian athletes who had received past doping suspensions from appearing in Brazil.
However, despite a previous 16-month suspension after testing positive for anabolic steroids and a positive test for meldonium earlier this year, for which she was cleared, Efimova was ruled eligible to compete in Rio by the Court of Arbitration for Sport on Saturday, per BBC Sport.
