Moves to cut out the FBI appear to be in line with a pre-election memo drafted by his legal advisers and fits with Trump’s enduring suspicion that the agency is part of what, without evidence, he believes to be a “deep state” machine within the federal government bent on undermining him.
Trump administration does something obviously illegal and unethical
FBI: “Hey, that’s illegal, you can’t do that.”
Trump: “Look at this deep state organization trying to prevent me from doing my job”
“hearing about all that stuff makes me uncomfortable, and I personally didn’t do anything wrong”
This is literally the argument.
