World swimming federation confirms US federal investigation into Chinese swimmers' doping tests

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. World Aquatics confirmed to The Associated Press that Brent Nowicki “was served with a witness subpoena by the United States government.” In May, a House Committee on China asked the Justice Department and the FBI to launch an investigation under a federal law that allows investigations into suspected doping conspiracies even if they occurred outside the U.S. The swimmers were allowed to compete at the previous Olympics in Tokyo despite testing positive for a banned heart medication.
