OKLAHOMA CITY (AP) — A Republican lawmaker's discovery of a magnetic box containing a high-tech tracking device affixed to the bottom of his truck is being investigated by Oklahoma officials, who also revealed that four other GOP legislators have reported concerns they were being followed. The mysterious discovery has stunned Oklahoma's political class, and raised questions about who would spy on lawmakers. "This is outrageous behavior and very reckless and foolish, and it could lead to somebody getting hurt," Oklahoma County District Attorney David Prater said Wednesday, adding that the tactics could lead to felony stalking charges.
