This should be very interesting.
Justice Dept. Opens Domestic Spying Probe
Curious choice of words, the real headline when following the link is "Justice Dept. Probing Domestic Spying Leak". Slight difference.
UPDATE: Looks like the DoJ has also opened an investigation of the leaking of the CIA prisons to the Washington Post.
The Justice Department has also opened a probe into whether classified information was illegally disclosed to The Washington Post, which reported on a network of secret CIA prisons in Eastern Europe and elsewhere.
How nice of the Washington Post to mention that they are being investigated in the body of an article about the New York Times being investigated.
