There was always the argument to made that it would cause an unholy stink in the press. That's the one that the bowtie rufflers go with. Certainly a fight with the press scares the crap out of them and being half way to being SJWs themselves, they instinctively project.
But if Trump was worried about a press fight why would he...?
Fill in that blank for yourself. You can start with, "run for president," then add, "fire Comey" and finish with "just get up in the morning."
So why would he care about firing Mueller, a man that was hired to railroad him for a crime that he didn't even get close to committing?
Apparently he knew something I didn't and that something was named: Peter Strzok
According to another source, with direct knowledge of the Jan. 24 interview, McCabe had contacted Flynn by phone directly at the White House. White House officials had spent the “earlier part of the week with the FBI overseeing training and security measures associated with their new roles so it was no surprise to Flynn that McCabe had called,” the source said.
McCabe told Flynn “some agents were heading over (to the White House) but Flynn thought it was part of the routine work the FBI had been doing and said they would be cleared at the gate,” the source said.
“It wasn’t until after they were already in (Flynn’s) office that he realized he was being formally interviewed. He didn’t have an attorney with him,” they added.
Strzok was removed from his role in the Special Counsel’s Office after it was discovered he had made disparaging comments about President Trump in text messages between him and his alleged lover FBI attorney Lisa Page, according to the New York Times and Washington Post, which first reported the stories. Strzok is also under investigation by the Department of Justice Inspector General for his role in Hillary Clinton’s email server and the ongoing investigation into Russia’s election meddling. On Saturday, the House Intelligence Committee’s Chairman Devin Nunes chided the Justice Department and the FBI for not disclosing why Strzok had been removed from the Special Counsel three months ago, according to a statement given by the Chairman.
