NBC newsman David Bloom, who was one of 600 journalists embedded with U.S. and British forces in Iraq, died over the weekend while covering the war. He was 39. Bloom's death was not combat-related; he died after suffering a blood clot possibly caused by immobility. Colleagues reported that Bloom had complained of leg pain from sitting in one position for hours in a tank. On Sunday's weekend edition of Today, where Bloom served as co-anchor opposite Soledad O'Brien, a solemn Matt Lauer and Katie Couric joined O'Brien in paying tribute to their fallen colleague. "He was a dedicated, tenacious and talented reporter," said O'Brien. "He died doing what he loved, and doing what he did best." Bloom is survived by his wife, Melanie, and three daughters.
