Dafur Refugee
President Bush says he's frustrated with what he called the United Nations' inaction over the violence in Sudan's western region of Darfur. He told reporters that the UN had failed to act to end genocide in Darfur, and insisted the world body did not have to wait for an invitation from Khartoum to deploy troops in the region. Host Marco Werman gets more on the story from Jan Egeland, the UN's humanitarian chief.
