U.S. Vice President Joe Biden's son is undergoing tests after he was hospitalised in Texas on Monday (19Aug13).

The Democrat politician and his family were enjoying a vacation last week (ends18Aug13) when Beau Biden fell ill.

After seeking medical attention at hospitals in Chicago, Illinois and Philadelphia, Pennsylvania, the 44 year old was admitted to a facility in Houston, Texas on Monday (19Aug13) to undergo further testing.

A statement from the White House reads, "This morning, the vice president accompanied his son Beau Biden to Houston, Texas, where Beau is being evaluated to determine the cause of an episode of disorientation and weakness that he experienced while on vacation with his family last week."

Attorney/politician Beau Biden was previously treated for a mild stroke in 2010.
