Then, we have Giuliani’s call to request that certification be delayed as long as possible (edit: I’m being told this call happened later in the day, after the rioters had been cleared out. It’s still an interesting voicemail and shows that Giuliani wanted the vote to be delayed):
Put it all together, and I believe that Giuliani wanted the delay so that all the representatives were guaranteed to still be in the building. Their plan was the taking of representatives hostage, delaying any sort of law enforcement response as long as possible, and trying to force some sort of reckoning. It’s thanks to the Secret Service that our representatives were not taken hostage.
