What does Trump have to hide?
The Great Obama released all his returns
No matter what might or might not be in his tax returns, Progressives would scream that something was wrong with them and demand he be impeached.
Of course, failed former President Barack Hussein Obama released all his returns. He never had a meaningful job. He once had a job as a lower level attorney at a firm where he was introduced to and worked on the accounts of their clients, Rod Blagojevich now serving time in prison and Tony Rezko also now serving time in prison. Tony Rezko helped the Obama's purchase their mansion in Chicago.
Beyond that, he's worked for the government.
