The stumble began as Biden was jogging away from center stag

I guess he was jogging up the stairs to Air Force One when he fell up the steps a couple of times. I guess he was jogging down those stairs in Japan a few weeks ago when he stumbled down the steps and almost fell into the Japanese Prime Minister.

You left out that he was getting ready to jog as part of a triathlon he was doing when he fell off his bike in Delaware.
