I think it makes more sense to look at it from the perspective of the press, which has shown its intense hatred of Trump as well as a singular inability to get a single fact straight. They would be unable to understand anything in his tax returns. That being the case, they would likely bring in "experts" to go over his returns.
When that happens, all facts and truth would go out the window. I think it would be safe to replace the word "experts" with something along the line of "political hacks with just enough knowledge of tax law to do a hatchet job on Trump and try to convince the American people he's guilty of something he didn't do."
Yep, that's it.
