Plenty of ammo for Trump to shut the whole thing down; the people will be behind him.
I believe you are right. Trump could fire Rosenstein and Mueller right now and we’d all stand firmly with him on it. Jeff Sessions probably would not, though. He might resign. But, at this point, eff him if he did.
Wait until the day after the elections. He’ll sweep them all out from Sessions on down.
That's the problem - only people who pay attention or watch Fox News have heard any of this. Most people have only heard the MSM telling us that the Mueller probe is moving forward and that there was Trump-Russia collusion (besides which, Trump says/tweets bad things about the courageous MSM). To most of the people in the US, there is no ammo that they have seen.
