Taking on the plight of refugees — and the misperceptions

Samantha Power, the U.S. ambassador to the UN, says the tens of millions of refugees around the world should be embraced, not feared.

She notes that more than 800,000 refugees have been taken in by the U.S. since the 9/11 attacks and none has been involved in domestic terrorism. Judy Woodruff sits down with Power.
