WASHINGTON (CN) - Ohio Congressman Dennis Kucinich says he suffered permanent injuries from biting an olive pit hidden in the sandwich wrap he bought at a House of Representatives cafeteria. He demands $150,000. The former presidential hopeful sued Restaurant Associates, which operates the cafeteria in the Longworth Office Building, its parent company, Compass Group USA, and food suppliers Performance Food Group Co. and Foodbuy LLC. Kucinich seeks damages for negligence, in Superior Court.
