WASHINGTON (AP) — Democratic congressman Dennis Kucinich of Ohio has sued a congressional cafeteria for dental damage he says he suffered after biting into an olive pit in a sandwich wrap he bought there.Kucinich's attorney, Andrew Young, declined to comment Wednesday on the lawsuit seeking $150,000 in damages from companies involved with the Longworth House Office Building cafeteria.The suit says the wrap "contained dangerous substances, namely an olive pit" that a consumer would not reasonably expect to find in the product served. The suit says that Kucinich suffered "serious and permanent" dental and oral injuries requiring multiple surgical and dental procedures.Kucinich's lawsuit says the Ohio Democrat bought the sandwich on or about April 17, 2008.
