Really? Those are the only "possibilities" to you?...there's not, like, an option that goes a little something like this: "President Trump isn't legally required to, and it's none of your business?"
Or,
"If President Trump is suspected of something illegal on his taxes, then the IRS can investigate; and since the Obama IRS didn't investigate him after he submitted his taxes, there's a very good likelihood there's absolutely nothing evil going on, whatsoever."
.
Those two possibilities never entered the picture for you, huh?
