Justin Gatlin, a sprinter on the USA team, has had some shade thrown at him from a teammate who is bringing to light a doping scandal from the athlete’s past.

After running the fastest time in the 100-meter heats, Gatlin’s teammate and 100-meter breaststroke gold medalist, Lilly King, questioned his right to participate in the Olympics this year, given his history with doping.

The swimmer has publicly spoken up about her distaste for athletes who have failed drug tests in the past and today (August 13) shifted the focus back onto Gatlin.

“Do I think someone who has been caught for doping should be on the US team?” she said during an interview. “No, I don’t.”

The sprinter hit back proving her comments aren’t taking away from how he feels about his achievements, saying, “I don’t even know who Lilly King is.”

“She does swimming and not track and field,” Gatlin added. “I’m not worried about that. I have confidence in my policies that I’m with.”

Gatling has previously been punished by serving a lengthy ban for his drug usage in the past and has since remained committed to being clean.

“I have come back and done what I needed to do,” he said. “I’ve worked hard, just like everybody else, and I get tested, just like everybody else. I'm back here. I believe in the system. I hope everybody else believes in the system too.”

Hopefully his teammate's comments don’t result in the athlete losing his focus, as he continues to compete in this summer’s Olympic Games this weekend.
