A white substance was found on a ballot envelope in Salt Lake County, Utah and was sequestered, tested and found to not be harmful, AP reports according to police.

Utah Lieutenant Governor Deidre Henderson, who oversees elections statewide, commended the county clerk and her employees for acting swiftly to ensure the safety of those in the area.

“This incident will be fully investigated. Anyone attempting to intimidate election workers or disrupt election administration in any way can expect to face criminal charges,” Henderson said.
