Beau Biden, the vice president's 41 year-old son and the Attorney General of Delaware, is in the hospital. For some reason. The White House just released the following mysterious statement (Updated below):

"Delaware Attorney General Beau Biden is at Christiana Medical Center undergoing treatment at present. He is alert and awake, and communicating with his parents and his wife, who are with him. We will provide more details as they become available."

UPDATE: Wilmington's CBS affiliate reports: "Sources tell Eyewitness News the 41-year-old son of Vice President Joe Biden is undergoing treatment for an apparent stroke." But ABC News reports: "A source close to the family tells ABC News that Beau had some discomfort this morning and a headache so he went to the doctors to get checked out. He's at Christiana Hospital and doctors are examining him trying to determine what, if anything, may be wrong."

UPDATE 2: From ABC News: "Biden has what the doctors 'believe to be a mild stroke, according to [his doctor]. '[He is] fully alert, in stable condition and has full motor and speech skills.'"
