'My sons were my redemption': The moving graduation speech that Joe Biden gave just weeks before Beau, 46, died of brain cancer

Biden told graduating seniors that 'reality has a way of intruding' in life and he shared the story of how a car crash that killed his wife and one-year-old daughter made him realize his sons needed to be his first priority, commuting four hours a day from Washington to Delaware so he could be with them for breakfast and dinner. Beau Biden's death was announced by the family on Saturday night.
