The U.S. basketball team returned to training camp Monday night after nearly a week off. And with games coming soon, it looks like this session is going to be a little more serious.

"We had a great practice, really hard," U.S. coach Mike Krzyzewski said. "Really hard."

Before Krzyzewski put them through a long workout at UNLV, the 15 returning players were first treated to a speech at their hotel from Sen. John McCain, giving the team an emotional boost before they took the floor.
