Statement from NBC Nightly News anchor Brian Williams:

When I lost my own Sister to breast cancer, Tony was among the first to contact me to offer comfort. He faced his own struggle with the bravery of an infantryman. He was a rare combination of true believer and honest broker — and that is why the death of this humane, beloved young man has been greeted with such widespread sadness.

And this from NBC News president Steve Capus:

We've lost one of the most prominent and respected voices in the American political and media landscape. Tony Snow made an honorable and real commitment to public service, even as his own health concerns loomed.

Tony's love for America and his family was always on full display. He also taught all of us enduring lessons in strength and determination as he waged a courageous battle against cancer.

On behalf of NBC News, our thoughts and prayers are with Tony's family.
