The House select committee on China has urged the Justice Department and F.B.I. to investigate allegations of a cover-up by Chinese authorities regarding positive doping tests for nearly half of their swim team at the last Olympic Games. The committee invoked a 2020 law to prosecute those aiding athletes in doping at international events. This move could increase pressure on authorities to scrutinize China's athletic program and the World Anti-Doping Agency before the 2024 Summer Games. The committee also sought an independent investigation by the International Olympic Committee, emphasizing the need to address these allegations before the upcoming Olympics.
