Haven't looked at the timeliness of the 6th but all reports besides msm seem to say entry of capitol began while Trump was still speaking. Once people entered they began to escort congress, in theory they would of started to call in reports to their dispatch of the incident. Why would the SS not of been notified of such an incident less than a mile away so that POTUS could be secured.

Seems like a rather large lapse of security or done intentionally to fit their narrative.
