I think you can rule out Rosenstein. I originally thought he was "ok", but... Did you watch his testimony this week? Unless there is some extraordinarily arcane plan here which involves him looking as much like he's lying as possible, he IS lying. About 98% of FReepers can figure it out themselves, just by watching, for the other 2%, search on You Tube for "Body Language: Rosenstein Mueller Expansion ".
Yes, I watched 100% of Rosenstein’s testimony.
I found it completely consistent with a law enforcement professional with no intention of talking about an investigation in progress.
But ALL the innuendos said the targets are not who the Congressmen all assume they are.
So ... I don’t know if that puts me in a 2% category ... but, the way I see it Rosenstein is doing EXACTLY WHAT TRUMP WANTS him too.
Playing to the long game to WIN, while the President chums the water with his Tweets.
