Well for starters he let the ladies off on the HRC investigation. He edited Comeys original memo to make sure HRC didn't get in trouble. 
First, that's wrong on a number of levels. Nobody "let the girls off." I explained why, and showed my work. Whatever he did or didn't do, he did not and could not do it on his own. 
But what does that have to do with Trump?
Then he was one of the lead interrogators for Flynn. With his obvious bias I'm sure he was very professional in that setting. You can expect Flynns indictment to be thrown out after all this is over .
I'm still missing the malfeasance here. Did he falsify evidence or something? Or maybe was he was just in the room when Flynn lied.
But I don't even think that PS is about the Trump ivnestigation. That part will be solved once they show that the Dossier was the lead and potentially only piece of evidence used to get the FISA warrants. When that happens then the probe will be finished.
That is an entirely different tune than you were singing before.
