David Bloom, an NBC News correspondent covering the war with Iraq as an embedded journalist, died of a pulmonary embolism - a blood clot in the lungs - Sunday morning. It wasn't clear Monday what caused the clot. But he had spent long hours riding and sleeping in cramped military vehicles and reportedly had complained of cramps behind his left knee three days before his death. Medical authorities say long trips in tightly confined spaces can lead to a blood clot that can travel to the lungs.
