Trump's Defense Secretary Christopher Miller send a memo to DCNG days before Capitol Riot to disarm National Guard.
"Without my subsequent, personal authorization, the DCNG is not authorized the following:
To be issued weapons, ammunition, bayonets, batons, or ballistic protection equipment such as helmets and body armor.
To interact physically with protestors, except when necessary in self-defense or defense of others, consistent with the DCNG Rules for the Use of Force.
To employ any riot control agents.
To share equipment with law enforcement agencies.
To use Intelligence, Surveillance, and Reconnaissance (ISR) assets or to conduct ISR or Incident, Awareness, and Assessment activities.
To employ helicopters or any other air assets.
To conduct searches, seizures, arrests, or other similar direct law enforcement activity.
To seek support from any non-DCNG National Guard units."
In other words, National Guard was authorized to stand down and stand by, while Trump cultist's ransacked Capitol building and tried to seek and incite violence against Democratic party members.
It really does seem like Trump's plan was to have the riot go so badly he could try to declare some sort of emergency powers to stay in office and halt the certifying the Electoral College Vote.
