To reporters: "I join in these expressions of condolences to Tim Russert's family. This was a great guy, a great journalist and the truth is he made us all better. He was tough on 'Meet the Press,' but I never felt he was out to knock down government or politicians. He was trying to make us all better, and I think he really did that. We're going to miss him a lot."
California Gov. Arnold Schwarzenegger
"[California first lady] Maria [Shriver] and I were deeply saddened to learn about the death of Tim Russert. Tim was an American icon in the world of political journalism who could relate to everybody. His insightful commentary and tough but fair interviews helped millions of Americans better understand our political system. It is hard to imagine a presidential election without Tim and his trademark graphics and questions on 'Meet the Press.' American politics and journalism will never be the same without him.
"But Tim was not only one of the top journalists of his generation; he was a close friend, a warm and generous person and a wonderful family man. Our thoughts and prayers go out to his wife, Maureen, his son, Luke and his entire family."
CIA Director Mike Hayden
"Like so many Americans, I knew Tim Russert as a dedicated, thoughtful journalist. His passing is a loss for our country and for all who hold dear the principle of a press that is free, vibrant, and responsible. Tim embodied those qualities, which he combined with a powerful sense of decency and kindness. Having had the privilege of appearing on 'Meet the Press' this past March, I saw his gifts as a reporter and interviewer. Tim knew that the good, brisk exchange of ideas could make any issue -- including sensitive and complex intelligence issues -- accessible to the American public. He was a true patriot, devoted to the education of his fellow citizens. At this time of grief, my thoughts and prayers are with Tim's family and friends."
Barbara Cochran, president of the Radio-Television News Directors Association and former executive producer of "Meet the Press"
To ABC News Radio: "He can be credited with revitalizing the Sunday interview format and making things that happened inside the Beltway terribly relevant and terribly important too all Americans."
