I asked what it matters. I have an opinion like everyone else which makes them pretty common. Not sure why getting me to admit I was wrong would be anything special.
I believe that you have certain rights to privacy even when you are the president. The IRS has his tax returns and if they dont find anything illegal then he doesnt have anything to hide IMO. There is no requirement that a president release his taxes. Furthermore, he has said that once the audit is over he will release his taxes. I am waiting for the IRS to get off it's ass and remove any excuse Trump has since even though he shouldnt have to he did state that he would release them.
Again though, this is small stuff... What does it matter if he is worth 1 billion or 10 billion. And what does it matter how much in taxes he has paid if he has followed the law? What is it exactly you think you are going to find?
