"Beau Biden served as attorney general of Delaware and joined the Delaware National Guard in 2003. He was deployed to Iraq in 2008, the same year his father ran for vice president. It was at the 2008 Democratic Convention he delivered an impassioned speech to introduce his father." Very sad news. Our thoughts are with his family tonight.
