Thueson believes there is no reason the community should be worried or alarmed.
Hazardous material crews are on-scene at an Idaho senator's Twin Falls office to investigate a white powdery substance found in an envelope by staff.
At about 9:30 Monday morning, staff at Sen. Jim Risch’s office discovered the suspicious envelope containing the substance and called Twin Falls Police Department.
Officers responded to determine and identify the white powder and quarantined the office. The white powder has not yet been identified. Four people are inside the senator's office.
Twin Falls Police Lt. Terry Thueson told KMVT none of the staff were injured or feeling ill.
The Twin Falls Hazmat team was mobilized shortly after the initial call. A hazmat team from Boise is en route and the FBI is assisting with the investigation.
The Falls Avenue entrance to the plaza is blocked while crews are on-scene.
