Question for all the lawyers out there:
I came across this suggestion that Pat Robert's upcoming "investigation" into the Fitzgerald probe and whether or not the intelligence community provides too much cover to its members may become a vehicle whereby Rove, Libby and associates could be given congressional immunity as a means to shield them from prosecution, ala North and Poindexter. Putting the conspiratorial tone of the piece aside, could something like that happen in legal terms or would it be pretty extraordinary?
It seems like the Roberts hearings are geared towards putting the blame once again on the CIA so I don't know why Rove or Libby would be brought in as witnesses. Furthermore, I've always thought that much noted political hacks Judges Sentelle and Silberman really pulled the North and Poindexter acquittals out of their asses but obviously other legal commentators have mentioned the problems caused by competing investigations.
Update: Say, since we're talking about Pat Roberts (R-WH) have a look at his greatest hits via Carpetbagger.
