Statement from CNN/U.S. president Jon Klein:

"Tony Snow was a highly respected colleague and a friend to many of us. The intelligence and warmth he brought to every conversation will be missed and the example he set of professionalism combined with humanity will be long remembered. He loved this country and its people and was looking forward to getting out into America to listen to their stories and share them with the rest of us. It is all of our loss that he never got the chance to do so. We regret that he was not a part of our CNN family longer, and our deepest condolences go out to his family."
