What the hell happened with Trump? He made all sorts of promises to drain the swamp and put Hillary in prison. He hasn't done that, in fact, he seems to have put the entire thing on hold.
You would think that Trump has all the information he needs, via his allies in the NSA, FBI and CIA (they can't all be against him, and all it takes is one or two with access to get all he needs). These agencies have recorded every phone call, email and electronic emission these people have made.
If he were to have Sessions convene grand juries to indict members of congress, do you think the judges would stop him? We've already seen what they did with his immigration limits. How many of the judges themselves are pedophiles? Many if not all of these would be thrown out of court.
You might say, why doesn't he just have someone leak the evidence? That's not the kind of evidence you can leak. Evidence of this would be child porn and doing the leaking would be an act of disseminating child porn. Evidence graphic enough to immediately disgust the public would be child porn and most people wouldn't look anyway. And you can't really tell people about it either. They aren't going be believe anything anyone says anymore, in fact, some Democrats don't believe proof you put right in front of their eyes.
For sure that's part of the situation bogging Trump down right now. What's the solution? I don't know. I'm not educated in legal matters.
