Two sources confirm (Editor and Publisher) that documents Time turned over to a Federal Judge name Karl Rove as one of the sources for Matt Cooper’s piece outing Valerie Plame. How key he was, and what information he provided, remain to be seen.
The White House said, back in 2003, that whomever leaked the info (if they were White House employees) should be fired and prosecuted (AmericaBlog). I expect that the coming weeks will see some creative definitions for “fired” and “prosecuted.”
