I mean Mueller did pass this to Congress, basically the Dems to do the right thing. Now, you can say Mueller is an upstanding guy by going by the book, yet its going to be a mess for any investigation or procedures against Trump.
I know what you are stating. This is truly a perilous time in our Democracy. The whole "can't indict a sitting President and up to Congress" should work and be the principle of our democracy. I'm a pessimist and see this just running out its last year and half.
