All the fencing and securing of perimeters isnt to keep Congress locked in it's to make sure leftists don't riot and actually storm the capitol when it turns out Trump will be President.
Why fortify DC so heavily if you are worried about Trump supporters? Shouldnt they be deployed to different state capitals where the right wingers live? DC is 95% democrat.
According to the Constitution. Due to their insurrection, any participants in congress and the senate have forfeited their offices. There is no legit legislative branch. They perform for the dumbasses who watch msm. Hoping the mob will save them?
