US President Joe Biden, 80, "is fine" after a fall that seems at first glance not serious. The Democrat had just handed out diplomas to students at the Colorado Air Force Academy.

Joe Biden then got up with the help of a soldier at his side and his bodyguards. He was seen pointing to this bag, obviously used to ballast a device on the scene, as if to explain the reason for his fall. But the damage is done. There is a lot of mockery and questions about his physical and intellectual capacity to perform his duties.
