During his tenure with NBC, Bloom reported on major stories including presidential races, the September 11 attacks, the Washington-area sniper shootings, and the war in Bosnia. According to the late Tim Russert, former NBC Washington bureau chief, "You couldn't keep him away from a story. Whenever something was breaking, he wanted to be there." In March 2000, Bloom became co-anchor of "Weekend Today" along with Soledad O'Brien, a position he served until his death.
