M.D. Anderson Cancer Center is the third hospital Delaware Attorney General Beau Biden has entered in less than a week.  The 44 year old has been undergoing medical tests, though their nature hasn’t been revealed.

Biden is the son of Vice President Joe Biden, who accompanied him to Houston.  He first went to a Chicago hospital when he felt weak and became disoriented during a family trip to Indiana.  He transferred to Philadelphia to consult with his doctor.

Beau Biden suffered a mild stroke three years ago. 

The Vice President had intended to return to Washington yesterday, but he decided to spend an additional day in Houston to remain with his son.
