No, I don't think Judge Sweeney cares, per se, about what Rosner or Begala say. I think she cares very much if the tweets trigger a breach of protective order claim as was launched by government over the reports that Parrott took the fifth. And I think she will care very much if the government uses the tweets as justification to file an appeal on her motion to compel ruling in a higher court.
To say that comments in this board will affect judges or trial testimony is just plain pathetic. I feel sorry for him if he really believes it. I don't think he does.
