This, basically Trump had to go through the gauntlet and get stuck with a list of sleazebags who were moved up the chair by the very people who started the Russia hoax. He managed with great effort to retain his position and over time expose a huge list of evil inside players one after the other, almost always with proof and usually in their own words.

Wray's probably already prepared his own resignation on Trump's order at some earlier date. I'm sure he knows he's the Resistance's top guy right now though, so he will do some of what Trump wants, or try to appear like it, in order to keep his own position.

But I also suspect that there's a whole unseen military intelligence aspect to all of this which we will never see, unless we absolutely have to. I can only hope they are even more agitated with the absolute state of the US government than we here are.
