It's probably something that he and his staff realized later was too quotable, like his "I don't take any responsibility" remark. I wouldn't be surprised if during the COVID talk she talked about elderly deaths and he shot back with "old people don't matter," or "let them die, no one cares," only to realize later that was going to be a huge soundbite that would be making the rounds in these final days leading up to the election.
I'm sure to this day the "I don't take responsibility at all" soundbite is something all of them regret. It became iconic.
