All you do is Google crap in an attempt to sound smart. In Morrison v Olson, Chief Justice Rehnquist's opinion for the court set limits. Morrison's office was limited in jurisdiction whereas Mueller's is not.
Mueller is behaving like a principle officer...even going so far as to charge Manafort with crimes unrelated to the specific scope of the appointment. That is WAY too much power for ANY inferior officer to have. He is basically behaving like a U.S. Attorney. He is more powerful than the 93 appointed ones.
Like I said, you turn a blind eye to this because you'll do ANYTHING to discredit or dismantle the President because you lost.
