A man with such troubles shouldn't be making speeches, especially at this late stage.If we're going to allow Trump to clarify his statements time and time again, we should allow the same for a man with a well documented stutter (something that gets harder to cover as you age, which is why it's once again become very prominent in the past few years).
People can watch the video regardless of who posted it and make their own mind up.
I'm sure team Kamala was right on it to get Biden to reclarify what he said. He's managed to scupper one angle that was working well for them to be critical of team Trump. Although I doubt Biden wrote a word of his explanation.
I await the community note.
