Reporter: This is how most Americans met beau Biden, the picture of health, embracing his famous father at the 2008 democratic convention. I am beau Biden and Joe Biden is my dad. Reporter: Joe Biden, now grieving for the second time over family dying too soon. When beau was just 3, he and his brother survived a car crash that killed his mother and sister. Incredible bond I have with my children is a gift I'm not sure I would have had, had I not been through what I went through. Reporter: Those words coming just two days before announcing beau was in the hospital for a recurrence of brain cancer. Difficult to treat, even more stubborn if it comes back. Beau, twice elected as attorney general of Delaware, lost his battle on Saturday night. A father knows he's a success when he turns and looks at his son or daughter and know they turned out better than he did. I'm a success -- I'm a hell of a success. Beau, I love you. Reporter: Tonight, friends of the Bidens say they are relying on faith and family to survive. No funeral plans announced yet. David? Jim Avila tonight from the white house. Jim, thank you.
