One feature of Democrats winning the House back in 2018 is the subpoena power that came with a whiff of congressional leadership. Now in charge of House committees, Democrats have been aggressive in their pursuit of Trump administration malfeasance wherever it may occur. That’s all fine and good, but Trump’s taxes remain the real investigative prize not named Mueller and, on Wednesday, the House Ways and Means Committee officially upped the ante in its pursuit of the president’s conspicuously buried taxes by formally asking the IRS to turn over six years of Trump’s personal and business tax returns.

Rep. Richard Neal is the chairman of the House Ways and Means Committee and instead of threatening Trump with legal action, the Massachusetts Democrat is “invoking an authority enshrined in the tax code granted only to the tax-writing committees in Congress that gives the chairmen of the House Ways and Means Committee and the Senate Finance Committee the power to request tax information on any filer,” the New York Times reports. “The provision, which dates in some form to the Teapot Dome scandal of Warren G. Harding’s administration, at least on its face gives the Trump administration little room to decline a request like Mr. Neal’s. It only says that the Treasury secretary ‘shall’ furnish the information.”

Republicans have, predictably, pushed back against the request, arguing that Democrats are “weaponizing our nation’s tax code.” The obvious counterargument is: it’s near impossible to weaponize something that is already in the public domain, as the taxes of every other president since Nixon have been. Trump addressed the move Wednesday afternoon with more of the same, claiming that he’d love to help, really, but he’s terribly busy being audited or something.
