"I guess getting the VP on the stand would be some sort of moonbat fantasy. And they might get a friendly judge, but who's going to allow this to continue while Fitz is still continuing his unending investigation?"
The moonbat fantasy part is too true. I don't, however, believe there is any law preventing a civil case from going forward while a criminal suit is ongoing.
It could complicate things for somebody like Libby. If you have actually been indicted then it probably in your best interest to just shut up.
Administration officials are under severe pressure not to claim a fifth amendment privilege against self-incrimination. Libby needs to not help the prosecutors any further by making statements that might contradict anything else he might have already testified.
Forcing Libby to take the fifth may be the goal of filing this suit. Then the MSM can ask "What does he have to hide" rather than consider the Fifth Amendment as vital to freedom as the First.
