WILMINGTON, Del. (AP) — Vice President Joe Biden is in Houston while his son, Delaware Attorney General Beau Biden, undergoes medical tests Tuesday.
The younger Biden, who is undergoing tests to determine why he experienced weakness and disorientation last week, posted a smiling photo of his wife and himself to his Twitter account Tuesday morning. The tweet said: "Touched by all your well wishes--thank you. Nice evening in Houston w/ Hallie; will share update when we have it."
Beau Biden, who suffered a mild stroke in 2010, began experiencing the new symptoms last Wednesday night after driving to Indiana for a family vacation, said Jason Miller, a spokesman for the Delaware Department of Justice.
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. He 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, but Miller declined Tuesday morning to say exactly where the testing was being done.
The White House said the vice president had been home in Delaware for the past several days and accompanied his son to Houston. It's not clear how long the vice president will stay, but he's scheduled to join President Barack Obama in Scranton, Pa., later this week during Obama's two-day bus tour.
Biden's Twitter account on Sunday posted a photo of him and his father sitting on a porch and smiling while sending a message of encouragement to a Delaware team that was in the Little League World Series.
This isn't the first health scare for the younger Biden, who became Delaware's attorney general in 2007. After suffering a mild stroke in May 2010, he spent a week in the hospital and more than a month recuperating at home.
"I was just a little off," Biden later explained to The Associated Press when asked about his stroke. "My arm didn't feel right. I was able to move it, but I just wasn't myself."
"Stroke was the farthest thing from my mind when I went in," Biden added then, saying he didn't know enough to be scared, or to reflect on the brain aneurysm that nearly killed his father in 1987 at age 45.
