Just sent out by the campaign:

"Our thoughts and prayers go out to the family and friends of Tony Snow. He was a loving father, husband, friend and truly one of America's most gifted commentators. Whether he sat behind a radio mic or stood behind a White House podium, Tony Snow always sought to give the American people new insights into our government, political process and leaders. He asked the tough questions and took them as well. Even when diagnosed with cancer, his fight served as an inspiration to all Americans. In the coming days, we will celebrate the life of a truly great and generous man."

UPDATE: This from President Bush:

Laura and I are deeply saddened by the death of our dear friend, Tony Snow. Our thoughts and prayers are with his wife, Jill, and their children, Kendall, Robbie, and Kristi. The Snow family has lost a beloved husband and father. And America has lost a devoted public servant and a man of character.

Tony was one of our Nation's finest writers and commentators. He earned a loyal following with incisive radio and television broadcasts. He was a gifted speechwriter who served in my father's Administration. And I was thrilled when he agreed to return to the White House to serve as my Press Secretary. It was a joy to watch Tony at the podium each day. He brought wit, grace, and a great love of country to his work. His colleagues will cherish memories of his energetic personality and relentless good humor.

All of us here at the White House will miss Tony, as will the millions of Americans he inspired with his brave struggle against cancer. One of the things that sustained Tony Snow was his faith - and Laura and I join people across our country in praying that this good man has now found comfort in the arms of his Creator.
