The breach of the capitol was proberly planned well in advance. I'd imagine the "recess" from the building being stormed was planned to happen much earlier in the day, so early that pence wouldn't have to say anything to show his position and none of the members would get a chance to argue the vote. POTUS orders patriots to DC and invites all to his live speech, delays the speech by nearly an hour and speaks for ages. Can't send off antifa to carry out the attack as planned because all MAGA watching the speech, would make it too obvious. Not only that, having many maga on the ground gave much more recorded video angles of everything. Also easier for whitehats to camouflage in a huge maga crowd.
