USA Swimming’s CEO is urging the U.S. Olympic and Paralympic Committee to push for the postponement of the Tokyo Olympics until next year.

Tim Hinchey wrote to USOPC CEO Sarah Hirshland on Friday to advocate on behalf of his governing body’s 400,000 members.

Hinchey said athletes’ worlds have been turned “upside down” as they struggle to find ways to continue preparing and training for the games. He wrote that “pressing forward amidst the global health crisis this summer is not the answer.”

Because of the disruptions in training, Hinchey said going ahead with the Olympics this year “calls into question the authenticity of a level playing field for all.”
