We see America's character in Bill Krissoff -- a surgeon from California. His son, Nathan -- a Marine -- gave his life in Iraq. When I met Dr. Krissoff and his family, he delivered some surprising news: He told me he wanted to join the Navy Medical Corps in honor of his son. This good man was 60 years old -- 18 years above the age limit. But his petition for a waiver was granted, and for the past year he has trained in battlefield medicine. Lieutenant Commander Krissoff could not be here tonight, because he will soon deploy to Iraq, where he will help save America's wounded warriors -- and uphold the legacy of his fallen son.

In citizens like these, we see the best of our country - resilient and hopeful, caring and strong. These virtues give me an unshakable faith in America. We have faced danger and trial, and there's more ahead. But with the courage of our people and confidence in our ideals, this great nation will never tire, never falter, and never fail.

 It has been the privilege of a lifetime to serve as your President. There have been good days and tough days. But every day I have been inspired by the greatness of our country, and uplifted by the goodness of our people. I have been blessed to represent this nation we love. And I will always be honored to carry a title that means more to me than any other - citizen of the United States of America.

And so, my fellow Americans, for the final time: Good night. May God bless this house and our next President. And may God bless you and our wonderful country. Thank you. (Applause.)
