We watched 9, yes 9 congressional investigations of Benghazi.  When the first one turned up nothing, they had a second one, when the second didn't turn up squat, they had a third, and so on.  Yes, eventually those investigations turned up the email server, but it took them years to get to that point.  You now think that somehow Congress will conduct a non-partisan investigation of Trump and the election?

If it were up to the Rs, they would have asked "Mr. Comey, how was your drive in this morning?"  No matter his answer, they would have declared that his answer proves no collusion.  

An independent counsel, one who has no political motivations is the only way to clear this up.
