U.S. swimmers Lilly King and Annie Lazor finished second and third in the 200m breaststroke, an admirable finish for the swimmers who were bested by a world-record setting effort by South Africa's Tatjana Schoenmaker.
Team USA's Ryan Murphy also secured a silver medal in the 200m backstroke, but garnered more attention after he then suggested that the race was tainted by doping, according to The Associated Press.
Murphy's teammate Michael Andrew was notably without a mask after his fifth place finish, and after the U.S. Olympic and Paralympic Committee said he violated protocol, they later reversed their decision, according to USA Today.
