This is yet another "in the fullness of time" things. I just hope they have something that can be done in the next couple of years or it dies.
Remember, Trump was trained by daddy to never to keep anything in writing - its a criminal rule. Destroying any evidence is a thing he seems to have done with regularity. We have been told he burns them, flushes them down the toilet, etc. Its about the only thing he hasn't screwed up yet.
