So Rove waited until Miller testified to add his 2-cents. Dollars-to-doughnuts that Rove testifies that it was Miller that told him about Plame/Wilson.
No. As this article states, Rove offered more testimony in July. A blogger reports (take with a grain of salt but he's being borne out and it makes more sense than the idea Libby and Rove violated any laws) that Rove gave a written proffer back then of his proposed testimony and it involves Matt Cooper.
Well, at post #230 someone linked to the New York Times story and surprise surprise surprise, they say it is indeed about Cooper.
Mr. Luskin has said he had offered for Mr. Rove to return to the grand jury if needed to clarify any questions that were raised by the testimony in July by Matthew Cooper, a reporter for Time magazine, who was questioned about a conversation that he with Mr. Rove regarding Mr. Wilson's trip in July 2003.
