(Reuters) - The U.S. Anti-Doping Agency said on Tuesday that the World Anti-Doping Agency must be overhauled to restore confidence in the global body ahead of the 2024 Paris Olympics following its handling of a Chinese doping case.

USADA wants an independent prosecutor to review the case of 23 Chinese swimmers who tested positive before the Tokyo Olympics began in 2021 but were not punished as WADA accepted Chinese authorities' explanation that their samples had been contaminated.
