I’ve never believed it was Trump supporters who planned the actual siege. It was definitely Antifa who planned it; they were saying on social media they were going as Trump supporters and do so.
I think 95% of the Trump supporters who were there expected to wave their flags and yell ‘rabble rabble’ and probably hear some speakers and sing songs until the vote count was done & announced.
Probably even more than 95%. Many of those MAGA people may have never been to a Trump rally nor to DC much less into the capital building. Such a sad ending to what had been a positive day until then.
