Investigating the Investigator

Taking the ball from Kos, Josh Marshall runs it down the field:

Sen. Roberts doesn't have time to investigate the manipulation of prewar intelligence, the Niger forgeries or the Plame disclosure.

But he does have time to investigate how the CIA uses 'cover' in its clandestine operations. And as part of his new exercise in water-carrying he will also investigate Patrick Fitzgerald's criminal probe.

Note the specifics: I didn't say he'll be investigating what Fitzgerald's investigating; he's apparently found time to investigate the Fitzgerald probe itself. Roberts' spokesperson Sarah Little told Reuters that his "committee would also review the probe of special prosecutor Patrick Fitzgerald, who has been investigating the Plame case for nearly two years."

Can any Senate Democrat not see now that Sen. Roberts only use for his committee is as a tool to defend the political interests of the White House? And will anybody deny that the decision to investigate Fitzgerald comes down on the orders of the White House?

My assist: I believe Josh is speculating that Roberts' may be using his power in order to intimidate Fitzgerald's investigation. But could it be even worse than Josh speculates? Could it be that Roberts is trying to use the subpoena power of his committee to determine what is going on within the Fitzgerald investigation? Might he pull an Ollie North and use congressional immunity to get damaging testimony about Plamegate out into the open so that that testimony cannot then be used by Fitzgerald in his investigation?

Don't put anything past these bastards.
