Longtime NBC anchor Tom Brokaw confirmed his death in a special report on NBC. Brokaw says Russert's death came during a political campaign that he loved.
Russert had been managing editor and moderator of "Meet the Press" and political analyst for NBC News, which he joined in 1984.
Before that, he had worked in the political world, serving as counselor in the New York Governor's office and a special counsel in the United States Senate.
