Beau Biden describes stroke

Delaware Attorney General Beau Biden is back in full campaign mode after suffering a stroke in May, and in an interview published Thursday, he reflected on the day he had a stroke.

"I remember it all," he says, adding that he believes he may have been a "little dehydrated and overcaffeinated" from the night before, when he ran four miles before putting his two young children to bed and staying up late to work on a broken chainsaw.

The next morning, something was wrong.

"I was just a little off," Biden explained. "My arm didn't feel right. I was able to move it, but I just wasn't myself."
