"We want to see some change for the future so you don't have to ask us that question," four-time Olympian Katie Ledecky said. On Wednesday, a journalist asked USA swimmer Katie Ledecky about Chinese swimmers being allowed to compete in the Paris Olympics, after several of them tested positive for a banned medication before the Tokyo Olympics. They avoided being banned in 2021. This year, according to World Aquatics, Chinese swimmers underwent increased drug testing before arriving in France.
