Jason Miller, a spokesman for the state Department of Justice, said Biden experienced the symptoms last Wednesday night after driving to Indiana for a family vacation. Beau Biden suffered a mild stroke in 2010. Biden, 44, was admitted to Northwestern Memorial Hospital in Chicago and traveled the next morning to Jefferson University Hospital in Philadelphia to consult with his doctor. Biden was discharged and spent the weekend at home in Wilmington. Miller said Biden currently is undergoing testing in Houston to determine the cause of his symptoms. The White House says Vice President Joe Biden, who had been at his home in Delaware for the past several days, accompanied his son to Houston. There was no word on how long the vice president would remain in Texas. Miller said Biden spoke by telephone to Chief Deputy Attorney General Ian McConnel over the weekend, and had been in touch with his office Monday evening. Biden became Delaware's attorney general in 2007.
