“The commander of the D.C. National Guard said the Pentagon restricted his authority ahead of the riot at the U.S. Capitol, requiring higher level sign-off to respond that cost time as the events that day spiraled out of control. Local commanders typically have the power to take military action on their own to save lives or prevent significant property damage in an urgent situation when there isn’t enough time to obtain approval from headquarters.”
“But Maj. Gen. William J. Walker, the commanding general of the District of Columbia National Guard, said the Pentagon essentially took that power and other authorities away from him ahead of a pro-Trump protest on Jan. 6. That meant he couldn’t immediately roll out troops when he received a panicked phone call from the Capitol Police chief warning that rioters were about to enter the U.S. Capitol. ‘All military commanders normally have immediate response authority to protect property, life, and in my case, federal functions – federal property and life,’ Walker said in an interview. ‘But in this instance I did not have that authority'” – Washington Post.
