Let's talk about the Michigan hearings from 12/02/20 (part one)

I watch the hearings from Dec 2, 20 and I have to say if I was the head of this committee after hearing these witnesses I would have wanted to at the very least look into these statements and either prove or disprove these statements. As far as I can see no investigation that has taken places. why?
