You do know why he didn't publicize his tax returns, right? His estimated inheritance was $150M in 2016 dollars, and his estimated wealth is $100M in 2016 dollars. He's managed to lose more than $1M a year. That's how he runs businesses, into the ground. Of course, he threatened to sue the biographer that detailed his finances, and the biographer said "sure, get on the stand in court, under oath, where the topic is your finances." Trump ran away and took back all his lies about the biographer.
Trump objects when you call him a failed businessman who has never made $1 in his life, but has just lost his father's fortune with style, but he won't show a tax return or open any books to prove it wrong.
At least fraud Hillary files her taxes and shared her returns.
Fraud Donald refuses to do that. And the Trump Worshipers can't think to ask why.
