Beau Biden, Delaware’s attorney general and son of Joe Biden, was hospitalized last week and is undergoing medical testing in Texas, his office revealed on Monday night. The 44-year-old, who suffered a mild stroke in 2010, was admitted to Northwestern Memorial Hospital in Chicago last Wednesday when he felt weak and disoriented after driving to Indiana for a family vacation. Biden was home over the weekend, and now he’s being evaluated in Houston, with his father by his side.
