Bill, nobody knows what they will find if they don't see them. The question is, what is being hidden? If you hide something from me then I can only assume there is something you don't want me to know.
You're speculating that we wouldn't find anything... If I'm wrong then what has been lost? However, if you are wrong...
The question isn't "what is being hidden?" The question, once again, is why do you need to see them?
To go the Fuzz route...
Do you think Trump is doing some illegal shit? Assuming arguendo he is, do you think he'd actually put that illegal shit on his tax return?
Do you think his Schedule B shows, "Interest Income - Loan to best pal Vlad"? Do you think Trump's properties are all owned by him personally?
Do you think maybe, just maybe, a guy who's been in the real estate business for his entire life and made billions, while shielding himself from bankruptcies of specific companies maybe, just may have a little bit more complicated of an entity structure than listing all of his properties outright on Schedule E? You think maybe everything could roll up into minimal K1s through holding companies?
Do you think maybe you could look at his financial disclosure form and create an org chart to figure out what ends up on his tax return?
So no, it's not that he's "hiding" anything from you. It's not public information, there's no requirement to publish the information. He knows, 98% of the people looking at the tax returns will be dipshits who don't know what they're talking about, but will try to spin any meaningless item into a controversy.
For Christ's sake, Maddyke said they had Trump's "1040 form" and various articles repeated that. It's a "Form 1040" or maybe just call it a "1040".
"1040 form" is nails on a chalkboard and lets everyone know you don't know what the hell your talking about and have no business opining.
