This reporter is a moron (which admittedly is not too unusual a character trait when discussing the MSM). The last thing in the world Fitzgerald will want to do is get into the issue of Plame's covert status not only because it was non-existent at the time she sent her hubby on the trip to Niger, but also because getting into Plame's covert status will allow the defense to start subpoenaing all kinds of classified records that the gov't won't be willing to give up.
Which is why the person is not named. :)
