Swimmer Chase Kalisz wins Team USA's first gold at Olympics

Chase Kalisz got things rolling, claiming the first U.S. gold at the Olympic pool. By the time the morning was done, the powerhouse team had a whole bunch of medals. Six of them in all, quite a start Sunday for the Americans in the post-Michael Phelps era.

"I'm happy to be here and kick the U.S. off," said Kalisz, who won the 400-meter individual medley. There was room for others to shine, as well.
