To date, the cover-up has worked about as well as President Donald Trump could have hoped.

Almost four years after Trump declared his campaign for the presidency, and more than 30 months since he won that office, he has successfully kept secret almost all the things he wished to keep secret. How much debt does he owe, and to whom? How much of his income derives from people who do business with the U.S. government? How much of his income derives from foreign sources? Who are his business partners, and do any of them present ethical or national-security concerns?

These basics of post-Watergate official disclosure have all been suppressed.

Incredibly, even after the delivery of Special Counsel Robert Mueller’s report, the American people still have only the haziest idea of Trump’s business connections to Russia and Russians. Do those connections cast any light on why the Russian government was so eager to have him elected president in 2016? Perhaps that information is held somewhere within the Department of Justice or the FBI, but citizens and taxpayers can only guess.

John Yoo: Mueller left a gap. Barr just filled it.

If Trump has his way, the secrecy will continue for a lot longer. In the past few days, he’s filed suit to prevent his bankers from complying with a congressional subpoena. His secretary of the Treasury has defied a never-before-questioned law and refused to surrender the president’s tax returns to the House Ways and Means Committee. His attorney general mischaracterized the Mueller report, as Mueller complained in writing, and now has operational control over the ongoing criminal prosecutions bequeathed to the Justice Department by Mueller.
