I could care less about "how much", I want to know exactly where and who with.
Americans deserve to know about the person making decisions for them and the country.
The president isn't the only one making decisions affecting this country. We also have congressmen, senators, those in charge of the various federal agencies and members of the federal judiciary including the Supreme Court, especially members of the Supreme Court.
What do you suppose would happen if someone proposed a law that required every candidate for the congress and senate to provide his/her tax returns for the proceeding 5 years and every year afterwards while serving in office? Anyone who even thought such a law had the chance of passing should be confined to a mental institution. In fact, I can tell exactly how many senators and congressmen from either party would vote in favor: none.
Democrats want to get something on Trump. They hope they will find something in Trump's returns they can use to discredit him. It doesn't have to be something illegal or unethical, just something they can twist to make him look bad. The Democrats are masters of spin and deception. It's the only thing they do well.
This country is facing serious problems, both domestically and international In spite of record tax revenues, the massive and unsustainable debt is increasing dramatically; Obamacare is imploding; illegal immigration is creating chaos; our infrastructure is crumbling; our nation's intelligence institutions have been engaging in massive criminal surveillance of private citizens, members of the press and even the president for purely political purposes; our educational institutions are failing; the dollar is in danger of losing its status as the world's reserve currency; we are engaged in senseless wars in the Middle East and in spite of all of this – and more - the dimwit, arrogant and self-serving Democrat assholes' primary concern is for Trump's tax returns? What a bunch of losers!
Trump should do what Obama did: seal all of his records to prevent them from disclosure. Trump has more important things to do than deal with Democrat witch hunts and other shenanigans.
