Due to the Capital Police Chief being prevented from requesting assistance from the National Guard. He was denied at least 6 times.
The people who denied even making the request was both the Sergeant of Arms in the House and the Sergeant of Arms in the Senate. Guess who they answer, who their bosses are? None other than Speaker Pelosi and Leader McConnell....now why would they refuse to secure the Capitol? Why did we see the Cap police move the gates and allow protesters and rioters inside?
