Christiane Amanpour had one burning question for Bashar Ja-afari, Syria's UN Ambassador: "How do you sleep at night?" The CNN correspondent interviewed Ja-afari on Tuesday as members of Congress debated the U.S. response to the use of chemical weapons in Syria. During the interview, which grew somewhat heated at times, Amanpour asked: "How do you sleep at night, Mr. Ja-afari, defending a regime and government that has caused so much bloodshed and that has really crossed the line from any kind of civil war into weapons of mass destruction? Into one the highest crimes of international law? How do you personally sleep at night?" Click here to watch the exchange.
