House of Representatives Minority Leader Nancy Pelosi (D-California) delivered an emotional account of the crisis in Darfur, Sudan, which she called "a challenge to the conscience of the world," in an address hosted by the Center for National Policy last Friday. Pelosi visited refugee camps in Chad in February. She recounted the deplorable conditions that the people of Darfur are forced to live in, where refugees - including children and pregnant women -have to walk several miles for water and firewood and live in "inhuman" sanitary conditions.
