I watched a CNN interview this morning and their camera had a close up of Biden leaving the stage after the debate. Trump had already walked to the stage exit and disappeared but Biden was frozen by the podium with Jill at his side. She tried to walk him forward but he couldn't move so she had to step back and pull his hand to get him moving forward.
Then when they got to the short steps a producer came forward to take his other hand to help him down the steps because he was doing so poorly but he refused it. This is not a good look and I don't care what you think. He's no longer able to function at the level required to be president and Trump is only half a step behind him in that department.
I can't find that video but I did find this one with a different angle that shows it happen just not up close. Just watch the first 30 seconds of it.
This is a bit better.
