You know that they're going to argue that, along with why it was released over the opposition of the DOJ and FBI. But while I think that it's hardly a nothing burger I guess I had also expected more of a smoking gun. I have a problem seeing where firing Rosenberg or Mueller is justified based on this alone.
It's a question of what they knew. If they knew how dodgy the basis for their surveillance was, they should go. If they were misled by underlings, they should say so... convincingly. That saves Rosenstein, but leaves Mueller to pack up shop, because everything he's done started with surveillance drawn from falsely sworn warrants.
I would think that signing off on a baseless FISA warrant application — lying to a FISA judge — is a serious, actionable offense.
But what do I know. According to Comey, it’s no big deal, par for the course.
