OKLAHOMA CITY (AP) — An Oklahoma lawmaker who found a tracking device attached to his pickup truck last month is suing a private investigation company and an investigator who works for the company over the device. Discovery of the tracking device has shocked Oklahoma politicians, who are wondering who was spying. Rep. Mark McBride, a Republican from the Oklahoma City suburb of Moore, is suing Eastridge Investigations and Asset Protection and Eastridge investigator H.L. Christensen for unspecified damages of more than $10,000, according to an attorney for Eastridge.
