The international swimming federation says its executive director has been ordered to testify as a witness in a U.S. criminal investigation into the case of 23 Chinese swimmers who tested positive for a banned substance in 2021 yet were allowed to continue competing. [time-brightcove not-tgx=”true”] The news comes just three weeks before the Paris Olympics where 11 of the Chinese swimmers who tested positive for the banned heart medication three years ago are set to compete. A House Committee on China asked the Justice Department and the FBI on May 21 to investigate the case under a federal law that allows investigations into suspected doping conspiracies even if they occurred outside the U.S. Swimming’s world governing body, World Aquatics, told The Associated Press on Thursday that its top administrator, Brent Nowicki, was subpoenaed to testify in the investigation. “World Aquatics can confirm that its executive director, Brent Nowicki, was served with a witness subpoena by the United States government,” World Aquatics said in a statement to The Associated Press.
