A Noticeably Disoriented Joe Biden Finishes Speech Calling Himself A ‘Full Professor At UPenn’ Then Slowly Turns To Shake Hands With An Invisible Person

A confused looking Biden sticks out his hand and appears to shake thin air after falsely claiming in speech that he had also been a ‘full professor’ at UPenn for four years. The 79-year-old president claimed before the handshake fiasco that he had served as a ‘full professor’ at the University of Pennsylvania despite never teaching a class at the school, in yet another gaffe that has Republicans questioning Biden’s cognitive abilities.
