@cbsnews: A federal judge has rejected McDonald's request to dismiss a proposed class action lawsuit accusing it of defrauding consumers by misrepresenting the contents of its McRib sandwich. The plaintiffs accused McDonald's of intentionally shaping McRib patties with ridges to resemble pork ribs and make diners believe the sandwich contains rib meat. McDonald's has denied the allegations, maintaining the sandwich is made with 100% pork.
