He didn’t slip or even have a simple fall. He had a full-blown full-body face-plant.
What should also be emphasized here....b/c it compounds the Biden tripping debacle, is that Biden was
bounding up those stairs for all he was worth. This was the day he'd show the world how "spry" he is.
The Bounding Biden Act was very calculated....and apparently pre-planned.
Biden's flubs, forgetfulness, and his shuffling oldster walk have made him a target of derision.
Most significant was that after the first fall, he continued bounding up the stairs....then fell..... again and again.
He obviously had rehearsed the Bounding Biden Act and was incapable of reversing course.
Plus typical of a prog/lib's stupidity....he probably thought nobody'd notice that he tripped.
