A Wonkette operative informs us that John McLaughlin is the latest recipient of a "powdery substance." Workers in the building aren't locked down, but they can't get in back in once they leave.
So when it turns out to be, like, baking powder, who gets to shout, "WRONG!"
UPDATE: All clear, says our operative. Whew, etc, but: "On the one hand, who would want to knock off McLaughlin? On the other, it’s not like he’s Father Christmas. Nevertheless..."
