The various talking heads trying to address the mess Trump made of firing Comey have at times suggested that 'countless' FBI Agents have spoken to the White House to express their concern (which could, in fact, indicate that the White House was attempting to influence on-going investigations).
Yet another example in a long line of the White House lying. The FBI agents, who are people like you and I, with families and responsibilities, are trying to do a job. It's a job of investigating Treason, which carries severe penalties. Penalties that a certain billionaire doesn't want to face. Very much doesn't want to face. Considering that billionaire is your boss, that puts you in a very precarious situation.
Continue to investigate, threatening your boss, and bad things could happen. We've seen track records of Trump firing whole groups of people (remember the Justice Department).
The FBI agents as a group, both currently on the job and retired pretty much all have the same story to tell: The White House is, once again, lying.
What's Trump's strategy to deal with all this going forward? By taking his toys, and going home, refusing to talk with the media directly ever again until he's blue in the face.
He's claiming that he wants to do it "for the sake of accuracy". Yes, that'd be nice. A bit of honesty would be good too.
