January 6th Committee made up of all democrats. Republican committee not allowed to ask questions. Why are the Democrats not investigating the five hundred seventy-four riots from 2020 that created havoc after havoc upon cities across America? perhaps they are ignoring it since it was their base that was mostly doing it, or they lied saying it was mostly peaceful or they encouraged it like Kamala Harris the vice President did and Maxine Waters as well as several other Democrats have done.
