This is the direct quote from Mueller saying what Trump actually said.

In interviews with this Office, McGahn recalled that the President called him at home twice and on both occasions directed him to call Rosenstein and say that Mueller had conflicts that precluded him from serving as Special Counsel.

Where exactly does that say he said that Rosenstein has to fire Mueller?

You are hearing a prosecutor's version of events and even then Trump never explicitly told anyone to fire Mueller.

Every day he went on Twitter and said Mueller shouldn't have been appointed. What exactly is newsworthy or a big deal. Ultimately he didn't do it. That's the difference between what Nixon did and Trump did.

We have gone over the other points above this one. Read back what I said.
