Beau Biden, former Delaware attorney general and the son of Vice President Joe Biden, died Saturday after a battle with brain cancer, the vice president said in a statement.
"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," Joe Biden said in a statement Saturday.
Joseph "Beau" Biden III, 46, was hospitalized earlier this month at Walter Reed National Military Medical Center. He died Saturday evening surrounded by his family, the vice president's office said.
Biden was diagnosed with brain cancer in August of 2013, and he underwent successful surgery and chemotherapy treatment. This spring, he suffered a recurrence and sought treatment, the vice president's office said.
"Beau embodied my father's saying that a parent knows success when his child turns out better than he did," the vice president said. "In the words of the Biden family: Beau Biden was, quite simply, the finest man any of us have ever known."
Biden was attorney general of Delaware from 2007 to 2015. He joined the Delaware Army National Guard in 2003, where he served as a major and was awarded the Bronze Star. He served one year in Iraq, from 2008 to 2009, on deployment with the Guard.
Last year, Biden declined to seek a third term as attorney general and said he planned to run for governor in 2016. Biden was most recently with the law firm Grant & Eisenhofer.
President Barack Obama said he and Michelle were grieving, and called Beau Biden a friend.
"Michelle and I humbly pray for the good Lord to watch over Beau Biden, and to protect and comfort his family here on Earth," Obama said.
"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," Obama said.
