Tim Russert, NBC News’ Washington bureau chief and the moderator of “Meet the Press,” died Friday after a sudden heart attack at the bureau, NBC News said Friday. He was 58.

Russert was recording voiceovers for Sunday’s “Meet the Press” program when he collapsed, the network said. He and his family had recently returned from Italy, where they celebrated the graduation of Russert’s son, Luke, from Boston College.

No further details were immediately available.

I'm really bummed out. Russert was one of the greats.
