Michael Phelps calls Lia Thomas controversy 'complicated'; highlights need for 'level playing field'

U.S. Olympic swimmer Michael Phelps has weighed in on the controversy surrounding the University of Pennsylvania's Lia Thomas, calling the transgender swimmer’s recent success “complicated.”

“I believe that we all should feel comfortable with who we are in our own skin, but I think sports should all be played on an even playing field,” he said in an interview with CNN’s Christiane Amanpour late last week.

Phelps added that he’s unsure what an “even playing field” should look like.

“It’s very complicated,” he said.
