The World Anti-Doping Agency (WADA) has called on the U.S. Anti-Doping Agency (USADA) to strengthen its anti-doping measures, highlighting that 90% of American athletes compete without adequate protection under the anti-doping Code. Concerns from 32 international anti-doping organizations emphasize that U.S. athletes are being sent to major competitions like the Olympics without sufficient pre-event testing. WADA urges reforms, particularly focusing on college sports, which are seen as lacking proper oversight. USADA has rejected these claims, labeling WADA's letter as a diversion ahead of a report regarding 23 Chinese swimmers cleared of doping allegations. The ongoing tension highlights broader concerns about anti-doping practices in the U.S. and their impact on global sports integrity.
