Do you really not think he could personally stop her being charged?
I take it Dr. Wang is no WalMartian.
Do you really think he can or should if there was an infraction? Have you thought of the consequences of him stepping in? Imagine the questions created by having the President step in now and "pardon" her. We would all be wondering what else he has stopped, pardoned, excused or ignored. And I mean, Democrats specifically. It would be political suicide. He could pardon her when he leaves office w/no repercussions.
