It is broken hearts that Hallie, Hunter, Ashley, Jill and I announce the passing of our husband, brother and son, Beau, after he battled brain cancer with the same integrity, courage and strength he demonstrated every day of his life.

The entire Biden family is saddened beyond words. We know that Beau's spirit will live on in all of us - especially through his brave wife, Hallie, and two remarkable children, Natalie and Hunter.

He went on to become a major in the Delaware National Guard, fought in the Iraq War and was awarded the Bronze Star.

Beau later became Delaware's Attorney General, "He fought for the powerless and made it his mission to protect children from abuse," his father said.

"More than his professional accomplishments, Beau measured himself as a husband, father, son and brother.," the statement reads

"His absolute honour made him a role model for our own family. Beau embodied my father's saying that a parent knows success when his child turns out better than he did," Joe Biden added.

"Michelle and I are grieving tonight," President Barack Obama said in a statement.

"Like his dad, Beau was a good, big-hearted, devoutly Catholic and deeply faithful man, who made a difference in the lives of all he touched - and he lives on in their hearts."
