Michael Phelps on retirement: 'This time I mean it'

After coming out of retirement once before, skeptics wonder whether Michael Phelps might still compete in the 2020 Olympics in Tokyo.

After winning five gold medals and one silver at the Rio Olympics to bring his overall medal total to 28, Michael Phelps is calling it a career. 

But after coming out of retirement once before, some are wondering whether Phelps might still compete in the 2020 Olympics in Tokyo. Today Show host Matt Lauer was among the curious, and he asked Phelps about his retirement plans on Monday's show. 

"Four years ago, almost to the day, we sat in London and you said to me when I asked you if you were going to keep swimming, you said, 'Done. Done. Done,'" Lauer said.

"You're going to get the same response here," Phelps responded. "Done, done, done. And this time I mean it."
