A clot in Tim Russert's left artery led to his heart attack on Friday, an autopsy report has revealed. He suffered from asymptomatic coronary artery disease. Tim's physician was surprised, saying Russert had a stress test in April that came back normal.

Russert was paid tribute today on "Meet the Press", the show he hosted for the last 17 years. Tom Brokaw took over hosting duties for the day to show highlights of Russert's career and life.
