Also, these people knew exactly how to find the offices of Senators Clybourn and Pelosi. Apparently Pelosi's office is unmarked, nondescript, and pretty well hidden down a maze of offices. And Clybourn has two offices, a "public" one, with his name tag on it that he rarely uses, and his official one, which is obscured in a manner similar to that of Pelosi's. Attackers knew which one to choose. Some are suggesting that this indicates support from someone with insider knowledge of the Capitol.

Then there's the whole topic of Boebert and her obsession with carrying a gun around Congress in the days leading up to the event then tweeting their locations live during the incident. It looks like telegraphing in hindsight; like she knew what was going down.
