美奥运选手对个人医疗信息被俄罗斯泄漏做出回应

Several U.S. Olympic athletes have taken to social media to respond to disclosures from Russian hackers that show they received exemptions to use banned drugs.

The hackers published confidential information earlier this week that was gleaned from the medical records of gymnast Simone Biles, tennis stars Serena and Venus Williams and basketball star Elena Delle Donne.

Biles, a gold medal winner, has acknowledged her use of Methylphenidate, a stimulant used to treat Attention Deficit Hyperactivity Disorder, or ADHD. In a statement on Twitter, Biles said she was diagnosed with ADHD as a child. "I believe in clean sport, have always followed the rules, and will continue to do so as fair play is critical to sport and is very important to me."

USA Gymnastics, the national governing body for the sport in the U.S., issued a statement on Twitter saying, "Biles was approved for a therapeutic-use exemption" and that Biles "has not broken any drug-testing regulations, including at the Olympic Games in Rio."

Venus Williams expressed disappointment on Twitter that her private medical information was disclosed and emphasized she has followed the rules established by the Tennis Anti-Doping Program. "I am one of the strongest supporters of maintaining the highest level of integrity in competitive sport," she wrote.
