Final word: Talk of firing Mueller is not vaguely similar to bleaching servers, destroing 30,000 emials and beating Blackberries to death with a hammer. One is obstruction. The Trump examples are ultimately and only wishful thinking.

When Trump fired Comey,  that did not impede the Muller investigation because Comey was replaced.    If Mueller had been fired,  Someone in Justice would have taken his place  . . . .  no actually obstruction would  have occurred.  By contrast,  when Hillary stole her own emails,  that ended the opportunity to investigate those emails    . . ..   OBSTRUCTION.  When Hillary ran "bleach bit" on her server,  that ended an investigation of her server   . . . .  OBSTRUCTION.  When Hillary smashed her Blackberry phones and destroyed the Sem Cards,  that ended any possibility of investigation those items  . . . .   OBSTRUCTION.  NOTHING Trump did or wanted to do after the Mueller Investigation began,  obstructed or could have obstructed the investigation.  Let's not forget that Mueller FINISHED his investigation and cited his conclusions as to collusion.
