First of all, he's not going to fire Mueller. I know you dipshits on the left want to make everyone think he is but he's not. Having said that, maybe the man doesn't like being accused of something he did not do. Ever think of that? Would you not be a little irritated if a cop pulled you over without cause and made you sit on the curb for an hour like a criminal while he called in other cops to search your vehicle? You know damn well you would be pissed, and at some point, you would want to sue the bastards so drop the bullshit "If he has nothing to hide he shouldn't mind being subjected to a never ending criminal investigation" line. If you fuckwads had any integrity you would admit you have nothing and end the investigation but you don't, because it's the only thing you have to hinder progress and prevent the President from doing his job. You people are pathetic.
Well if you fuckwads had any integrity you would look at Trump's record of firing people- and realize that it is certainly within the realm of possibility that Trump will fire Mueller.
Of course Trump is irritated by the investigation- that is certainly clear.
But as far as 'nothing'- the roots of the investigation go back to a Trump campaign member telling an Australian diplomat in a bar that the Russians had dirt on Clinton.
We also know that Trump's son welcomed a meeting with a Russian that he had been told had dirt on Clinton.
What we don't know is what else Mueller has found so far.
You fuckwads don't want Mueller to continue his investigation.
What is it you are afraid he will find?
