So reports NBC Chicago, Lawyerist, Outside the Beltway, and Chicagoist. New York Magazine reports on a separate incident.
Actually, this news isn't very breaking. The first four reports I link to concern one of Scalia's remarks in October 2011. The New York Magazine report covers a remark that Scalia made to California Lawyer in January 2011.
So for everybody who has gotten all worked up over Scalia's recent remarks on deep dish pizza, you are unfortunately a bit behind the times. I'm looking at you, Time, New York Daily News, and Politico.
