Why is "Official A" the only person not identified by name or title in the indictment?
On or about July 10 or July 11, 2003, LIBBY spoke to a senior official in the White House ("Official A") who advised LIBBY of a conversation Official A had earlier that week with columnist Robert Novak in which Wilson's wife was discussed as a CIA employee involved in Wilson's trip. LIBBY was advised by Official A that Novak would be writing a story about Wilson's wife.
Why the secrecy around the identity of "Official A"? Why the deference to his anonymity? What's going on with "Official A" that isn't going on with anybody else?
