Previously, tensions between WADA and U.S. representatives escalated when Tygart accused WADA of concealing critical test results. The fallout extended to finances, with the U.S. halting its funding contributions, the largest among nations, due to skepticism regarding WADA's governance. In a further retreat, WADA also dismissed an ethics inquiry against Dr. Rahul Gupta, who represented the U.S. on WADA’s board. Gupta maintained he had no prior knowledge of any investigations involving the swimmer's tests.

The U.S. Anti-Doping Agency welcomed the dismissal, describing it as a “complete vindication” for themselves and Gupta, highlighting a shifting landscape in the global sports regulatory environment.
