Okay then, if she had no authority, the Sgt of Arms would have known and expected her to forward the request up the chain-of command, did she? Of course we don't know. Maybe she waited till things got underway which would explain the two hour delay.
But no, it turns out though that somehow the request for help made it's way to the DC National Guard Commander
THE DC National Guard Commander says the Pentagon took away authority to send in a quick reaction force to respond to Capitol riots.
The commander of the DC National Guard told The Washington Post that the Pentagon restricted his ability to send in a quick reaction force to respond to the Capitol riots. Instead, he had to get approval from high er-up the chain of command.
How high would that be ? The Oval Office guy is the last link in that chain. That's why he's called the Commander-in-Chief.
Also, I notice you had nothing to say about the FBI missing the chance to avoid the attack.
Sure sounds like people in high places didn't want a ready made crisis on a plate going to waste. Maybe cancel Donald Trump for good after four years of trying and failing?
