Hey! What about Novak??

Ok, so can someone please explain why Robert Novak wasn't arrested? And why is Judy Miller going to jail?

This is from AP:

"[Judge] Fitzgerald is investigating whether a crime was committed, and by whom, in the Bush administration's leak of the name of undercover CIA officer Valerie Plame.

Columnist Robert Novak first published Plame's name in July 2003, days after her husband, former U.S. Ambassador Joe Wilson, publicly disparaged President Bush's rationale for invading Iraq. Administration detractors said the leak was designed to punish Wilson for his criticism by ending his wife's undercover career.

Time magazine reporter Matt Cooper, who identified Plame after Novak, avoided the same jail term given Miller. Also held in contempt by Hogan for refusing to testify before Fitzgerald's grand jury, Cooper shocked the packed courtroom Wednesday by announcing that his source had contacted him just hours earlier to give him specific, unambiguous permission to tell the grand jury about their conversations.

Miller never wrote a story naming Plame, and there's been no official explanation why Fitzgerald wants Miller's testimony. The court rulings upholding his effort have blacked out details of his reasons. New York Times' attorney Floyd Abrams speculated Wednesday that "most likely somebody testified to the grand jury that he or she had spoken to Judy.""
