Vice President Joe Biden's son dies
US Vice President Joe Biden announced Saturday that his son Beau has died of brain cancer at age 46.
Beau Biden was a member of the Delaware National Guard and the Delaware Attorney General.
Earlier this month he was hospitalized at Walter Reed National Military Medical Center. At the time, the vice president's office refused to indicate the disease for which he was being treated.
Beau Biden suffered a mild stroke in 2010 and underwent surgery at a cancer care center in Texas in 2013 to correct what was described as a minor injury.
Last year he announced that he would not seek a third term as attorney general and instead planned to run for governor in 2016.
