Thank you, trf.
(speculating on IF KR is called to testify).
"You can go to the bank on Rove repeating his G[rand] J[ury] testimony--and he won't just repeat his "story": Wells will make sure that the jury understands that the unindicted Rove said the same thing to the G[rand] J[ury], if at all possible. And that will be a BIG hit to the prosecution. If, as we and just about everyone else suspects, Russert will end up having to unpack his highly nuanced testimony, the perjury rap will collapse at that point."
