Tim Russert, host of Meet the Press, died Friday. He was 58 years old.

While his network has not officially released the details, the New York Post claims the journalist died after suffering a heart attack at NBC News’ Washington Bureau. Russert worked there as the bureau chief.

Time recently named Tim one of the ‘World’s Most Influential People’. The magazine praised the news analyst for being one “among the most astute, discerning and relentless pursuers of truth in the nation.”

Russert joined the NBC News family back in 1984 and was Meet the Press’ moderator since 1991. No immediate announcement has been made about the fate of his program.
