Mr Trump is asked about his criticism and hostility towards the Black Lives Matter movement - but he insists he is the “least racist person in this room”, pointing to his record on criminal justice and prison reform.
“I can't even see the audience because it is so dark but I don't care who was in the audience. I am the least racist person in this room,” he says.
Mr Biden tries his hand at a joke but it’s lost in the fog of debate.
“Abraham Lincoln here is one of the most racist presidents we have had in modern history. He pours fuel in every single racist fire, every single one,” he says.
Mr Trump asks about the reference to Lincoln, and where it came from.
“I said, ‘not since Abraham Lincoln has anyone done what I have done for the Black community, I did not say I am Abraham Lincoln.”
Well that’s clarified.
