Re the Judiciary Committee looking at the FISA judge, I listened to the execrable Hugh Hewitt’s show this morning because he had Devin Nunes on. They talked about this very thing. Hewitt suggested going to Supreme Court because they have oversight of FISA court. Nunes said his committee is discussing ways to handle this without violating separation of powers. But Nunes also said he has confidence in Mueller. How can anyone have such confidence in light of all we now know? I think the fix to get Trump is still in place as long as Mueller stays.
Significant that you should mention that - you have, I am sure, considered the possibility that all we now know just might be incomplete or even incorrect (or a combination).
I think that some Republicans saying that they have confidence in Mueller is only somewhat genuine. In reality, this look inside the sausage factory is meant to pressure Mueller to do the right thing (in case he was inclined to take after his DOJ/FBI buddies and go hard after Trump despite how unfair it looks to how Clinton was treated).
Recall that Mueller enabled H Clinton’s Uranium one deal with Russia. Mueller is as dirty as any of these seditious perps.
