Former Delaware AG and potential 2016 candidate for Governor Joseph Robinette “Beau” Biden III passed away from brain cancer on Saturday at the age of 46. AG Biden, the eldest son of Vice President Joe Biden, announced in 2014 that he would not seek reelection as AG, but would focus on his 2016 campaign for Governor. AG Biden served as Delaware AG from 2007-2014. He was a Major in the Delaware Army National Guard and the JAG Corps, and served a tour in Iraq from 2008-2009. AG Biden is survived by his spouse, Hallie Biden, and his two children, Natalie and Hunter.
