Pro Publica: 

from the Sund interview, he now thinks the pipe bombs were meant to distract him & police from the site while Trump called on protestors to "fight" and Giuliani urged "trial by combat"

I am skeptical of trusting everything he says here. Keep in mind it is not under oath, it is him freely agreeing to interview with WaPo. After reading numerous accounts of how several Congresspersons really repeatedly interrogated all the three Capitol security boss men about being well prepared for this day, well in advance (including Maxine Waters-I was actually surprised to learn what a tough attitude she had about protests of any kind being heavily secured and policed.)

BUT ESPECIALLY after reading this about another guy in charge, Senate Sergeant at Arms Michael Stenger.  Amazing reporting from a shocking leak:

Amid the mayhem, a large group of senators were secretly led to a room in a Senate office building. Stenger was with them, and the furious lawmakers peppered him with questions.

“How does this happen? How does this happen?” demanded Sen. Lindsey O. Graham (R-S.C.)

Stenger could not muster much of an answer, practically inaudible as he dispiritedly debriefed the senators. “He was talking in circles,” Graham thought to himself.

Sen. Joe Manchin III, D-W.Va., called Stenger’s attempt to field that question “absolutely pathetic” and further reduced confidence in the room. As Graham pressed for a better explanation, Stenger’s voice got weaker and smaller.

“Here’s your mission: Take back the Senate,” Graham told Stenger. “Whatever you need to do, do it. We’re not leaving this place. We’re not going to be run out by a mob.”

Finally, the Senate sergeant at arms sat down amid the others in the room, saying to no one in particular: “I wish I had just retired last week.”

McConnell was determined to get back to the floor. “We are going back tonight” to finish the vote to formalize the election, he said at one point. “The thugs won’t win.”

By 6 p.m., a perimeter around the Capitol was secured.
