Subject: Re: "Totally innocent" Trump
If there is one sure thing that we can take to the bank, it’s that no SCOTUS would ever overturn established law.

A fair point, but this one didn't do that. They could have held in Trump that the materials were privileged from discovery in the first place, rather than merely inadmissible afterwards, but they did not. Which makes it somewhat less likely that Trump (or anyone else) could expect them to do so in the timeframe relevant to his Administration.
