It has been more than a month since Sen. Bernie Sanders (I-Vt.) told a national audience during a CNN town hall that he would release 10 years of his personal taxes “soon,” adding, “We have to do just a few little more things.” Five weeks later, it seems those “little” things still aren’t done; he told CBS on Sunday that “we have it all done and it’s just a question of dotting the i’s and crossing the t’s.”

Enough with the excuses, Senator. These sorts of shenanigans — and make no mistake, that’s exactly what they are at this point — both reduce the pressure on cowardly congressional Democrats to pursue President Trump’s personal and corporate tax returns, and endanger Democrats’ hopes of taking back the presidency in 2020. The progressive positions that Sanders champions, including Medicare-for-all, expanded Social Security and increasing the minimum wage to $15 an hour, are much too important to both the future of our country and our own personal finances to risk them over tax returns.

Trump broke with decades of precedent in refusing to make his tax returns public when he was running for president. The result? Not only don’t we know our president’s net worth, we also have little idea how he earned his fortune or how he makes his money now. Minus his paperwork, it’s hard to determine whether Trump is using the White House as a just-in-time moneymaking opportunity, violating the emoluments clause of the Constitution, and/or even paying his fair share of taxes at all.
