obama can pardon anyone and Trump can undo.
Can you site an instance when a President unpardoned someone that was pardoned by another U.S. President?
Technically speaking President Trump will not be prosecuting anyone... That’s the job of his Attorney General Senator Jeff Sessions who is very by the book when it comes to the law. Why do you think the media is having a conniption fit about Senator Jeff Sessions? They know he will prosecute Hillary.
Finally do you really think a guy like President Trump during the campaign and debaters said he would let his AG look into Hilary? This is just the latest divide and conquer. Remember many of the same people told us Trump would not build a wall. Well it’s in the plans now. So much for that argument.
