Tuesday (Aug. 16): Lochte tells USA Today that the swimmers didn't initially report the incident to the IOC "because we were afraid we'd get in trouble."

Saturday (Aug. 20): In an interview with NBC that aired on Saturday, Lochte cites his own "immature behavior" for turning an incident involving unruly actions by the four swimmers into an international incident. "That's why I'm taking full responsibility for it, because I overexaggerated that story," Lochte told NBC. "If I'd never done that, we wouldn't be in this mess. Those guys would never be in Rio, or were in Rio. None of this would have happened. It was my immature behavior." The 11-time Olympic medalist, Lochte has said he hopes to compete at the Tokyo Olympics in 2020.
