Washington (CNN)Joseph "Beau" Biden III, an Iraq war veteran who served as the attorney general of Delaware and was a son of Vice President Joe Biden, has died at the age 46, the White House said in a statement Saturday night.
He had battled brain cancer.
Beau Biden had been receiving treatment at the Walter Reed National Military Medical Center in Bethesda, Maryland, according to a statement released Tuesday by the vice president's office. He had suffered known health problems dating back to 2010, when he experienced a stroke that did not affect his motor skills or speech.
In 2013, Beau Biden was treated at a hospital in Houston that specializes in cancer care after he became disoriented and weak while on vacation. He later underwent surgery to have a brain lesion removed.
Throughout those episodes Beau Biden continued serving as Delaware's attorney general, a position to which he was first elected in 2006. A Democrat like his father, he served for two terms, and announced in 2014 he wouldn't seek another four years in office as he prepared a run for governor.
