'We are very blessed': Michael Phelps visits TODAY after welcoming second son

Swimmer Michael Phelps, the most decorated Olympian in history, is using his retirement for good causes, including water conservation. He tells TODAY that “we are very blessed” to have two young sons who love to be together, but adds that he doesn’t want to force Boomer and Beckett into athletics. He urges “common sense” about water conservation, like brushing your teeth in the shower.
