Why should he, so that more lies could come out of it from that crooked Hillary.

You want Trump's tax returns yet Hillary does not want to release her emails. All her staff pleads the fifth because they are very honest people. She racks in millions while she is in government and it seem okay with you. She pretends to care about women's rights and issues up until a dictator gives her hush money for a political favor. She has a foundation that she uses as money laundering. Oh yes I forgot it's a charitable foundation that keeps 90% for the Clinton's and 10% for good causes. I guess all this cool.
