Mr. Libby didn’t leak Ms. Plame’s name to journalist Robert Novak; Mr. Armitage did that deed, though neither he nor his close friend, Mr. Powell, bothered to tell Mr. Bush or the world. Based on the trial record and our own long experience with Mr. Libby, we also don’t think Mr. Libby lied. As Mr. Fitzgerald’s prosecution circled back again and again, Mr. Libby’s defense that his memory faltered in recalling the details of long ago conversations is entirely plausible for a busy White House aide.
The case against him was based on conflicting accounts of a single conversation Mr. Libby had in July 2003 with each of three journalists. The judge threw out the count concerning his talk with Judith Miller, and the jury found him not guilty on the count involving Matthew Cooper. His conviction on four other counts comes down essentially to a dispute over Mr. Libby’s claim that Tim Russert had told him about Ms. Plame. Russert, the NBC journalist who has since died, initially told the FBI it was possible he told Mr. Libby, but by the time of the trial Russert said he was sure he had not done so. Neither man had notes from their call, and it is possible that Russert’s memory was as faulty as Mr. Libby’s.
