When people behave as if they have something to hide, it is often because they do. For me, this is a basic law of human behavior.

That’s why President Trump’s baffling, outrageous, unfathomable and just plain bizarre behavior last week strengthened my already strong suspicions that there is something that Trump knows about the investigations into his campaign’s contacts with Russia that he doesn’t want us to know.

That is the only way that I can make sense of what happened: These are either the machinations of concealment, expressions of a burgeoning insanity, or both.

The details of the most recent episode in the Trump madness are now well known and yet every new detail that helps add texture to the story also renders it more horrifyingly egregious.
