Muller just shot himself in the foot.
I don't know how much the rest of you know about Exoneration (I'm an expert), but honor and shame are huge parts of it. It's not like it is in Democracy where you can become successful by being an asshole. If you screw someone over in America, you bring shame to yourself, and the only way to get rid of that shame is repentance.
What this means is the American public, after hearing about this, is not going to want to impeach the president, nor will they Impeach any of the GOP. This is HUGE. You can laugh all you want, but Muller has alienated an entire market with this move.
Muller, publicly apologize and cancel your report or you can kiss your career goodbye.
