[Trump apparently does not understand that the FBI works to enforce the law for the people,not for his political or legal well being, as so many Hillary supporters in Congress misunderstood this role last year.]
Trump continues to act like running government is like running a business.  That he could just fire and replace a problematic "employee" and that would be the end of it.
I just hope he learns from this that things are different but I've been saying that since his first days in office.  It's been four months so far and he keeps proving he isn't learning because he isn't capable of admitting to making a mistake in any way, shape, or manner.
