Bauer interrupts and shouts down Biden, who is trying to formulate his arguments for why he should be president.
Bauer is playing the role of Donald Trump during mock debate prep -- often embodying the President as he behaved during the first debate in order to prepare Biden stay on message in the event that Trump blows through new measures put in place by the Commission on Presidential Debates to prevent interruptions.
Team Biden is worried that the plan to mute candidates during portions of the debate will not help with the distraction factor. Even if the audience at home can't hear the President's microphone if he interrupts Biden, the Democratic nominee will be standing right there and will hear him loud and clear. Paying no attention to the man next to him is a significant part of Biden's prep for going into the ring with the President one last time.
Biden and Trump are heading into their final planned showdown of the 2020 campaign, with 12 days to go until Election Day.

Conway and other Trump advisers are renewing their argument to him ahead of the last debate that the more Trump let's Biden speak, the worse it is for Biden.
"Biden gets flummoxed fairly easily when he's trying to remember a contrived or practiced phrase or soundbite and let him do that. Let him have the airtime all to himself so people can really see what happens with Joe Biden when he's left just with them, the audience at home and Joe Biden's thoughts," Conway said.
Trump seems to at least be hearing that advice.
"There's a lot of people that say let him talk because he loses his train -- he loses his mind, frankly," Trump told Fox News this week.
But Biden allies push back on the notion that more Biden is dangerous for their candidate, arguing for example that during his town hall with ABC News last week, he was more cogent and clear when he was not constantly being interrupted.
