Tax returns have, um, returned to the top of our awareness.

Not my tax returns. Or yours. I refer to the president of the United States.

You’ll recall when Donald Trump stiffed 40 years of political tradition by refusing to release his returns for public scrutiny. He said dubiously that he was under audit by the Internal Revenue Service. That was more than two years ago! He still hasn’t released them. He is showing not a single indication that he’ll do so voluntarily.

Presidential candidates of both parties since 1976 have released their tax returns in the spirit of full transparency. Trump talks about being transparent, then hides his returns.

They’re increasing in relevance to what has developed. The special counsel, Robert Mueller, likely knows what is in those returns. He likely knows about whether the president has invested in “Russia matters.” He likely knows whether the president has benefited materially from his office, which could be in violation of the U.S. Constitution’s Emoluments Clause, the part that says presidents cannot accept money from foreign governments.

We’ll know in due course whether Mueller has those returns. We’ll know also in due course whether the special counsel has anything incriminating regarding those returns.

The idea that Trump has refused to release those returns because of an IRS audit falls apart on two levels. First, he’s never produced any evidence that the IRS is even auditing his tax returns. Second, the IRS — which doesn’t comment on individual audits — has made it clear that an audit does not preclude any public figure from making those returns public.

My direct plea to the special counsel is this: Make those returns available to those of us who want to know the truth behind our president’s financial dealings.
