I think you’re missing the forest for the trees.
The Statement of Offense IS extremely thin, but it’s only the visible tip of the iceberg. There’s simply no way Mueller would have given Flynn a pass on attending not one but two meetings to discuss the illegal rendition of a Turkish cleric in exchange for $15 million unless Flynn had something pretty valuable to trade.
The second release of the Statement made it clear Kushner is part of the proffer. But I suspect his father-in-law will prove to be in there too.
You dismiss that with reference to the speculation from Andrew McCarthy, but he’s an outlier on this topic. Most experts believe Mueller isn’t ready to show his hand on Trump, as there are still more witnesses to be flipped.
One of the things we learned from Watergate is “It’s not the crime — it’s the cover-up.” If indeed there was nothing wrong about Flynn’s contacts with the Russians, why lie about them — to both the FBI and, supposedly, Mike Pence? If Flynn had gone off the reservation, why was Kushner giving him the go-ahead? And would Kushner — who claims he used to spend 5 hours a day working with his father in law — do something that significant without mentioning it to POTUS?
It may surprise you to learn that I think it’s unlikely Trump was working hand-in-hand with the Russians to undermine the election. (My bet is this is all about sources of finance, and the possibility of a Trump Tower Moscow.) But if — as Trump effectively confessed in the supposedly lawyer-written tweet that went out today — he knew Flynn had lied but asked Comey to drop the investigation anyway, there’s a pretty good case for obstruction of justice.
In other words, collusion isn’t the only thing that could bring Trump down.
