Except we need somehow to reestablish in people’s consciousness the rule of law so that both parties abide by it not just one!
I think Trump needs to pick an outstanding Attorney General and then leave it up to the AG to decide how to proceed. Trump will have more important problems to deal with, and it should not be something that can be portrayed as a political payback to an opponent.
Remember the case of Spiro Agnew. He pled nolo contendere, paid a fine, and resigned his office. His crimes were penny ante stuff compared to Hillary, and he had the office of Vice President as a bargaining chip, but maybe something like that could be worked out. Of course the fine would need to be orders of magnitude higher. Perhaps $1,000 for each document that was destroyed and $10,000 for each classified document that was handled carelessly. But Obama may limit the options by giving her a pardon.
He can't pardon the Clinton Foundation. That investigation can proceed.
