May 30, 2015: Former Delaware Attorney General and son of Vice President Joe Biden, Beau Biden passed away from a brain tumor at the age of 46. A celebrated war hero, Biden had been seen as a rising star in the Democratic party. He was first diagnosed with brain cancer in 2013, but was thought to have made a full recovery. The cancer returned in the spring of 2015. He is survived by his wife Hallie, and his children, Natalie and Hunter.

In a statement, VP Joe Biden said, “More than his professional accomplishments, Beau measured himself as a husband, father, son and brother. His absolute honor made him a role model for our family. Beau embodied my father’s saying that a parent knows success when his child turns out better than he did.”
