It is a ball for folks who can’t afford the big ritzy celebrations - after the inauguration. Tickets cost $500 IIRC. It is also the ball that J20 was planning to throw vomit scented acid around and try to stampede people-as exposed by O’keefe in one of his undercover Veritas stings which took place at the infamous Comet Pizza.
So, the ball doesn’t start until tomorrow night? Why, then, are we looking at the ballroom now? What people are there, aren’t dressed for a ball.
