POTUS has this in the bag:

Speaker 11: (41:34) You know that it’s tradition for previous presidents to go to the next president’s inauguration. So will you attend Joe Biden’s?

Donald Trump: (41:40) I don’t want to say that yet.

Speaker 11: (41:41) But he is going to be inaugurated.

Donald Trump: (41:42) I mean, I know the answer, I’ll be honest. I know the answer, but I just don’t want to say it yet.

Speaker 11: (41:45) Is that a yes?

Donald Trump: (41:45) Look. A thing like this possibly has never happened before, but maybe people just didn’t catch it, but we’ve caught it.
