Michael Phelps has called for lifetime bans for athletes who test positive for banned substances, in response to a doping scandal involving 23 Chinese swimmers before the Tokyo Olympics. Phelps criticized the World Anti-Doping Agency (WADA) and World Aquatics for not making the positive results public until recently and allowing the athletes to compete, some of whom went on to win medals in the Paris Olympics. Phelps highlighted his own experience with rigorous testing to ensure he competed fairly, arguing that elite sports should maintain a level playing field. He received unexpected support from athletes like Conor McGregor and Nate Diaz. Phelps expressed concerns that the integrity of the Olympics is at risk if doping is not adequately addressed.
