President Trump doesn't have to publicly disclose his tax returns, now or ever. A release of the tax returns to the full House or Senate effectively would make the documents public. Justifying a public interest in Trump's tax returns might not be difficult. "I believe the powerful Ways and Means Committee has the responsibility to ... ensure proper oversight of the executive branch by requesting a review of President Trump's tax returns." The chance of a Republican-controlled Congress choosing to make a Trump's tax returns public, without his consent no less, seems very remote at the moment.
