After staring down Efimova in the ready room and giving her a look of disdain on the deck, King led all the way to take the gold with a time of 1 minute, 4.93 seconds.

Efimova, who heard a round of boos and a few cheers during the introductions, settled for the silver in 1:05.50. The bronze went to another American, Katie Meili, at 1:05.69.

King was critical of Efimova being allowed to compete in the Rio Games after serving a previous 16-month suspension for doping and testing positive again this year for the now-banned substance meldonium. Possible sanctions over a second violation were put on hold while WADA does more research on the drug.

King didn’t acknowledge Efimova during a raucous victory celebration. Finally, as the two were picking up their credentials at the side of the deck, King gave her rival a quick pat on the shoulder.
