Written statement: "There is no one who knew Tim, and that includes millions of Americans who felt they knew him too, who isn't deeply shocked and saddened by his death. Tim was everyone's idea of what a journalist should be and he made us proud. He interviewed me just one month ago for his weekly television show and much of our conversation had to do with his love for his father, Russ, and his son, Luke. My heart goes out to his wife, Maureen, and to Luke and Russ."
Cokie Roberts, ABC News
Written statement: "Tim Russert was a great competitor and a good friend. I am obviously shocked and dismayed by this news and extend my thoughts and prayers to his son Luke -- he was so proud of you -- to his wife Maureen and to the rest of his family, especially his beloved father. Tim and I worked together on Catholic causes, and I will greatly miss him."
Sen. Hillary Clinton, D-N.Y.
Written statement: "We were stunned and deeply saddened to hear of the passing today of Tim Russert. Our thoughts and prayers are with his wife, Maureen, his son Luke, his father who we all have come to know as Big Russ, his extended family and all of his many friends and colleagues at NBC who have suffered a tremendous loss. Always true to his proud Buffalo roots, Tim had a love of public service and a dedication to journalism that rightfully earned him the respect and admiration of not only his colleagues but also those of us who had the privilege to go toe to toe with him. In seeking answers to tough questions, he helped inform the American people and make our democracy stronger. We join his friends, fans and loved ones in mourning his loss and celebrating his remarkable contribution to our nation."
Former Vice President Al Gore, D-Tenn.
Written statement: "The U.S. and the world have a lost a great journalist, interviewer and author. He was an original and will be greatly missed."
Senate Majority Leader Harry Reid, D-Nev.
Written statement: "I was greatly saddened to learn of Tim Russert's untimely death. Tim was a warm and gracious family man with a great zest for life and an unsurpassed passion for his work. His rise from working-class roots to become a well-respected leader in political journalism is an inspiration to many. Tim asked the tough questions the right way and was the best in the business at keeping his interview subjects honest. My thoughts are with his family."
Sen. Charles E. Schumer, D-N.Y.
Written statement: "It is hard to comprehend and even get your arms around the fact that Tim Russert has been taken from us so suddenly. Just about every American thought he was part of their family, sitting around the kitchen table on Sunday mornings, talking about the country and its politics. I first met Tim Russert when he was working for Pat Moynihan, and even then it was clear he had a great mind, a big heart, and a twinkle in his eye. My thoughts and prayers are with his family today.
"Western New York, in particular, will miss Tim Russert because he was in every way Mr. Buffalo. Even when he was interviewing presidents and heads of state, western New Yorkers knew that his blue collar, Buffalo sensibility guided him throughout."
Sen. Chuck Hagel, R-Neb.
Oral statement: "He always instinctively knew what was important and what to ask. It was tough being on 'Meet the Press.' I always enjoyed it."
Sen. Joe Lieberman, I-Conn.
