I do think Trump is to blame because he is the one who called them to Washing with his "Stop the Steal" message when he knew there was no steal. Also he did nothing for hours to call that mob off. Even his own daughter asked to call them off.
When he finally did he told them to "go home, we love you."
I know the right wants to try to spin the blame to Nancy Pelosi. Pelosi did not have the power to call in the National Guard.
All of the rioters are criminals and should be held accountable.
