Novak finally spills the beans on 2 of his 3 sources (Karl Rove, Scooter Libby) that Valerie Plame (wife of amabasador Joe Wilson, who spoke out against the Bush administrations "facts" that Iraq was amassing yellow cake uranium from Niger for a WMD program) was a CIA agent... and he's protecting the 3rd sources identity, even though he doesn't have to. Interesting stuff.
