IF Rothenstein resigns.....I see what you did with he spelling you slanderous, ignorant POS..... Trump can appoint a replacement without going through a confirmation process.
If he fires him a confirmation process is required; which will both drag on for months and also hand Mueller yet another obstruction of justice charge.
There's that 'thinking things through' problem, again, that you can't seem to shake.
it cripples you in any fair engagement on the facts of any matter.
And it's way too late for you to do anything about it.
