Is the Plot Thickening?

As John Podhoretz theorizes at The Corner, what if Judith Miller is, in fact, the target of Fitzgerald's investigation?

The theory would jibe with the fact that Rove released all his sources back in 12/03 . . . so if Miller's source were the same as Cooper's, she'd be outta jail free.

Update: According to the Corner again, Cliff Kincaid from Accuracy in Media first presented that theory last night.
