Please don't make me defend Hillary.  She makes me sick.

 

She was found to have inadvertently put low level classified material on her personal server. She was an idiot for doing so

 

But that is not a crime that is usually prosecuted.  It is a crime that would get you fired if you worked for the FBI and should make it clear you are unfit to be President..

 

She never should have had a personal server, the point of which was to hide her communications.  And putting classified material there is incredibly stupid and careless. 

 

Trump is accused of intentionally taken top secret classified material  and lying about it.  That is a crime that is always prosecuted.
