That's the tu quoque fallacy. That someone else does an immoral thing doesn't excuse others who do immoral things. Mr. Obama is not at issue here, Donald Plump is.
No, it isn't at all. It's an indirect way of attempting to acquaint you with simple facts that you appear to be completely unaware of, by example. The President, via the DOJ, has a great deal of universally acknowledged and accepted discretion in deciding what "crimes" to prioritize/prosecute. Everyone knows this (except you, apparently).
You seem to be unaware of even 3rd great civics, demanding to know where in the constitution the President is given authority to preside over the executive branch of government.
