U.S. Vice President Joe Biden's oldest son, Beau Biden, left the hospital Tuesday, a week after he suffered from a mild stroke. Delaware Attorney General Biden, 41, walked out of Thomas Jefferson University Hospital in Philadelphia, accompanied by his father-in-law and carrying his 4-year-old son, Hunter. “Good to be headed home, Biden told media gathered outside the hospital before getting into a car. Biden will continue recuperating at his Wilmington, Delaware home, and it is unclear when he might return to work. Biden was admitted to Christiana Hospital in Newark last Tuesday and transferred later that day to Thomas Jefferson, the largest center in the region for treating strokes and aneurysms. Biden announced in January that he would not run for the Senate seat his father held for more than 30 years, but instead would seek re-election as attorney general.
