Ghost of Fitzmas Future?

In the course of courtroom arguments, prosecutors naturally fight vigorously to keep certain investigatory information not relevant to a case out of the record. But there was one noteworthy instance in the Libby trial wherein Patrick Fitzgerald made a pointed comment, the implication of which seemed to be that he had certain information held in reserve, for what may become evidence to be used in a subsequent prosecution. Today, Murray Waas for the National Journal explicitly declares If Libby is found guilty, investigators are likely to probe further to determine if Libby devised what they consider a cover story in an effort to shield Cheney. They want to know whether Cheney might have known about the leaks ahead of time or had even encouraged Libby to provide information to reporters about Plame's CIA status, the same sources said.
