CHICAGO (CBS.MW) -- Fire trucks were called Wednesday to the Chicago Mercantile Exchange (CME) after a report of a suspicious odor at 11:25 a.m. in the telecommunications room. Fire fighters treated several people at the exchange for "dizziness," but there were no serious injuries, said CME spokesman John Holden. "There was no impact on exchange operations," he added.
