We can do that after we get rid of Trump. If we let Trump do it now, he will turn it into a circus, gain some political cover from it, and we will never know for sure who actually did what.
Once we have sane leadership again, then we can do it properly.
That's kind of what I mean by "sane leadership." Leaders that know they are there to serve the people, and that they will be removed if they don't.
Of course, that requires sane voters, too.
