Trump has been reticent to release his tax returns for changing reasons.
"Previously, Trump blamed an ongoing audit for his failure to release returns, an excuse that was questioned by tax experts. As recently as Sunday, Trump pledged to release the returns “as fast as the auditors finish.” Last October, Trump said he would release his tax returns once Hillary Clinton released her emails. Now, Trump adds that he’s not planning to release them because “there’s nothing to learn from them” and voters aren’t interested in the information."

"Still, Trump has also refused to release his tax returns from previous years, which are no longer under IRS audit."
Should he release them? If not why not. If so why? Is he hiding something by not releasing them?
