An investigation is underway after authorities in Washington State say envelopes filled with white powder were mailed to multiple county election offices.
Authorities confirmed that at least one of the powder-filled envelopes tested positive for fentanyl, according to police in Renton and Spokane.
Spokane County reported receiving the envelopes just before 10:30 a.m. and Pierce County reported receiving theirs at 11:00 a.m. Wednesday.
The Renton Police Department told Fox News Digital it is continuing to coordinate with the FBI in an investigation.

"There were no employees at the elections' office that were injured or became ill from today’s incident. The employee who opened the envelope noticed the substance right away, placed a container over it, and pulled the fire alarm to evacuate the building," Cyndie Morris, Renton Police Information Officer tells Fox News Digital.
Morris says the envelope is now with the Hazmat team and that the FBI will continue to run an investigation.
"We will coordinate efforts w/the FBI, but our detective unit will move forward with the investigation in the meantime. Part of the investigation process will certainly include whether there were other election locations who experienced something similar, and if so, try to determine if there is a connection. It’s too soon to tell at this juncture," said Morris.
