Le Clos, once Phelps’s friend, said the American had “been talking a lot of smack in the media about how slow the butterfly is,” back in 2015. He doubled down on the criticism last year.
The medal is the 24th of Phelps’s career, and the 20th gold. In his fifth Olympic games, Phelps now has two medals, picking up gold in the men’s 4×100 meter freestyle relay on Monday.
He swims again on Tuesday night, in the men’s 4×200 meter freestyle relay.
