There was a whole industry making products for the day. High ranking politicians and big money financers paid for large bus trips for free travel and food. It wasn’t just to see Trump talk: they could do that any other place.
It was the day of the vote. They were there to stop it by force and declare Trump the true winner of 2020.
One financer was a very wealthy woman who inherited money from being the daughter of the creator of Publix supermarkets. She funded a lot of buses to go there.
She wanted to MAKE SURE Trump was put back as President.
