The Winter Olympics used to present a promotional challenge. Now there?s speed, danger and an Olympic team that is more identifiable to a more diverse cross-section of America.

In the meantime, these results present a challenge to policy makers.

I don't think we've ever beaten them. They're very athletic and will present a huge challenge.

This type of clear and present danger comes with too much violence for us to ignore at this early stage.

I think there's a danger if you try to hit it off the wall every time. But, ever since I was 6 years old I was a pull hitter, and my key is to look middle, and I'm going to pull because that's my point of contact.

The U.S. would like to take U.S.-China relations to the next level. The challenge ... is to show the American public that there's some result, that there's some productive output from this increasingly candid and strategic discussion between the two leaders.
