Hearing from someone who is privy to the inauguration day plans that Trump will only be attending a few balls (rather than the 8-10 normally attended by POTUS).
Also so far, the people performing at the inauguration ceremony are Jackie Evancho (National Anthem) and the Mormon Tabernacle Choir (singing a newly arranged version of America, the Beautiful with the President’s Own Marine Band).
No Hollywood prima donnas - yay.
Here’s a FR thread on the Inaugural activities. There are several balls, but only 3 “official” ones this year.
