Former President Joe Biden and his family made a surprise cameo on the set of the Amazon action series Reacher on Monday morning. According to the show's star, Alan Ritchson, the ultimate alpha male showdown saw Biden proving his dominance over the burly actor with his own flex of strength.

Joe Biden accidentally crashed the set of Reacher on his way to breakfast Monday in Philadelphia, inadvertently strolling onto the premises as crew members filmed a police chase scene for the fourth season of the Prime Video thriller.
