Authorities in Colorado are investigating a “suspicious, powdery substance” found in a ballot mailed to the Adams County elections office in what officials say “appears to be an attempt to disrupt the elections process.”

Hazmat units, paramedics, firefighters and other law enforcement agencies were called to the county offices after the ballot was received Wednesday, and initial testing of the substance was negative for explosives, biological agents and narcotics, Adams County clerk Josh Zygielbaum said Thursday.
