I saw the show on Saturday July 5, it appears the same as it was before with the exception of the speech as others noted. Most of it is a movie, main focuses on Washington, Lincoln (with the animatronic Gettysburg Address), Teddy Roosevelt, FDR from what I can remember. The end when they show all the president animatronics they say each president’s name and they do a little head nod. Then Trump just says the oath with no additional content.
Audience reaction was unremarkable. No cheers/boos or other political comments that I heard
