Joe Biden explained how he broke his foot to CNN’s Jake Tapper “What happened was I got out of the shower. I got a dog and anybody who’s been around my house knows — dropped, little pup dropped a ball in front of me. And for me to grab the ball, and I’m walking through this little alleyway to get to the bedroom. And I grabbed the ball like this and he ran. And I’m joking, running after him and grab his tail. And what happened was that he slid on a throw rug. And I tripped on the rug he slid on. That’s what happened. Oh man, not a very exciting story.”

The extent of Biden’s injury was not immediately clear. The Biden campaign broke the news on Sunday that Biden had twisted his ankle but later that day released a statement saying a CT scan “confirmed hairline fractures of Biden’s lateral and intermediate cuneiform bones, which are in the mid-foot. It is anticipated that he will likely require a walking boot for several weeks.”
