Swedish authorities are confused after a mysterious man on a Fox News feature was referred as the country's "defense and national security advisor." Swedish military and foreign-affairs officials said they have no knowledge of the man, who goes by Nils Bildt. Bildt spoke out about Sweden's crime and "socially deviant activity" during the Bill O'Reilly segment. Marie Pisäter at the Defense Ministry told the newspaper "Dagens Nyheter."
