O'Hare spy mission? A Chinese national is accused of lying to feds about pictures he took of aircraft at the Chicago airport. Those allegations are being made against Weiheng Zeng, 24, seen on numerous security camera videos in the cargo area. In one screengrab, the FBI said Zeng can be seen in a FedEx parking lot, up on a lift, snapping pictures of aircraft. But why? NBC Chicago Investigative Reporter Chuck Goudie has the story. #spy #chicago #ohare #airport #espionage #china
