Claressa Shields is a 17-year-old US boxer who scored a triple knockout at the 2012 Olympics. She's the first American to win gold in Olympic boxing. She won the first-ever women's boxing middleweight competition.
She was also the only American boxer - man or woman - to win gold in London AND she's the second youngest boxer ever to win gold. Shields received a very emotional hero's welcome home in Flint, Michigan.
This morning on "Early Start," John Berman talks with Shields about the thrill of winning gold and that little matter of sticking her tongue out at her opponent. See the interview in the clip above.
