Watch Matt Lauer Interview Ryan Lochte on Rio Incident: 'I Over-Exaggerated That Story'

"ALL WE KNOW IS THAT THERE WAS A GUN POINTED IN OUR DIRECTION, AND WE WERE DEMANDED TO GIVE MONEY."

Twelve-time medalist Ryan Lochte took "full responsibility" Saturday for the incident in Rio that landed him and three other American swimmers in hot water and tarnished Team USA's reputation during the 2016 Summer Olympics.

"I over-exaggerated that story," Lochte, 32, told NBC's Matt Lauer in an exclusive interview, a day after posting an apology online.

Lochte told Brazilian authorities — as well as Lauer — that he and fellow teammates Gunnar Bentz, Jack Conger and James Feigen had been robbed at gunpoint at a Rio gas station after a night of celebrating. As inconsistencies emerged in the account, skepticism grew.
