Ignoring the fact that the article is from a liberal pub, the gist of it may partially explain O'Donnell's comments (the Rove sending out info not the leaking part). The Prospect article basically says (hearsay) that Rove testified to the FBI the he and others sent out info on Plame AFTER Novak's article. So Time's notes may include info from Rove and others, but that does not make it illegal or wrong. It was after the fact of Novak running the Plame story.
Yes, it seems to be the source of his comments.
In other words... he's leaping to unfounded conclusions.... again...
