MUELLER MUST BE FIRED! Or Trump will go down. What the hell is he waiting for?
He's not. First he has to delegitimize Mueller. This is part of that effort.
Effectively done, Mueller will have to leave, or be fired by the weight of public and Congressional opinion.
Trump's on the right track. Everyone can see this as a set up now.
Absolutely must destroy Mueller totally and kill the investigation.
Not waiting doing nothing. Waiting until the right time to fire him. He didn't fire Comey on day 1. Instead he waited for the DAG to investigate Comey and write the letter. The letter is very good.
Trump will have a similar letter when he agrees to the firing of Mueller. An unimpeachable letter.
