Trump has so far managed to keep all doors into his life closed—except the one marked “E”

Many people have things to hide. Many of those people hide them with lies, distractions, obscurities, payoffs, threats or punishments.
Even some, maybe many, of his supporters suspect that Trump has things to hide, though those supporters may think he, good man that he is, is hiding them for good reasons.
Trump has managed to hide things or explain away whatever was seen as inconsequential or often as fake.
He knows, and those who know him know, that the door marked “E” is turning out to be a challenge. Which explains how much effort has gone into to keeping it closed and blocking the view.
In criminal law, when a defendant or witness invokes the Fifth Amendment right against self-incrimination, the instruction to the jury is that it may not infer guilt from that silence.
In life outside the courtroom, when someone tries to block the view of what actually happened, we do infer something from it. There is some possibility, we reasonably think, that blocking the view means that someone is hiding something.
The door marked “E” is opening a crack. We may see more if the congressional demand for complete FBI files is complied with, but there are many possible and likely obstacles to that.
Trump has managed to keep all other doors into his life closed so far, and has been very successful at it. If and when we get this door opened and see it all, we may be both astonished and unsurprised.
If and when.
