Never before has the Trump White House shown such transparency. There have been masquerades at it—stacks of paper arrayed when the president announced his supposed divestment plan, for example—but never the real thing. Even better for the White House, the messenger is highly credible, unlike the goofy Harold Bornstein, who examined Trump during the presidential campaign. Jackson is a respected doctor who took up his role during Barack Obama’s term, and Obama administration officials lined up to vouch for Jackson’s probity. There are reasonable questions to be asked—Is Trump stretching his height? How much does the Montreal Cognitive Assessment really tell us?—but Jackson’s reputation and detailed answers grant the report real gravitas.

In fact, not only has this White House never shown such transparency; perhaps no White House has done so. A briefing of this length and detail from the presidential physician is apparently novel. So, too, is the administration of the Montreal test, which Jackson said was a new addition to the regimen. That suggests that questions from critics about his mental fitness for the job got to the president.

It’s no surprise that given the good news and good messenger, the president would be eager for Jackson to visit the briefing room. But the sudden outbreak of openness raises questions of its own. Why can’t the administration always be this forthright? In particular, why can’t it be more open about the president’s finances?

Even as the president offers unusual transparency about his health, he remains far more secretive about his finances than any president since Watergate, which is especially notable because his finances are more elaborate and at greater risk of conflict of interest than his predecessors. Trump’s campaign claimed he could not release tax returns because he was under audit, but there is no legal reason an individual can’t release returns that are being audited, nor did the campaign ever offer any evidence he was really under audit. The campaign promised to release them later, but since the election the president has made clear he has no intention of releasing the returns, even as the White House makes highly dubious claims about how tax cuts might affect Trump’s own personal wealth.

The cynical reading is that Trump is willing to release his medical information because the results look good for him, and unwilling to release the financial information because it would look bad for him. But as Tuesday’s briefing demonstrates there’s an easy way to rebut that, and to get good press. Just release the returns and send Trump’s accountant to the lectern to field the questions that ensue. How about it, Mr. President?
