Special Counsel Robert Mueller’s investigation must be like water torture for Donald Trump. Every piece of news about it is another brick in the wall that will eventually encircle the President and, more importantly, his business interests.

The wall won’t imprison Trump. It is doubtful that he will even be charged with any crimes. What the wall will do is keep others away. By the time Mueller is done, Trump Inc. will be a toxic hot potato that no one will want to be close to.

Trump is very well aware of this. So every time Mueller puts a fair sized brick in the wall, Trump tries to tweet it away. “No collusion” tweets Trump – he’s got nothing, it’s a waste of time. No Brick.

But the truth is that very slowly and very methodically, the wall is taking shape. Mueller is laying as strong of a foundation as he can to make sure that the wall will stand up to any legal trebuchet that Trump’s legal team can conceive of. So far, it looks pretty solid.
