In a Meet the Press interview, on July 24, 2016, Donald Trump reiterated that he would not release his tax returns until auditing them was completed. He indicated that his auditing of his returns started 14 years ago. It was unclear whether Trump was claiming that one of his returns has been under audit for those 14 years or whether every year his returns get audited. Either way he did not indicate that he would release any returns that have been audited in the past 14 years.
Meanwhile, Hillary Clinton has 33 years worth of returns posted on line, with no problem viewing, whether or not audited.
