Envelopes containing 'white powdery substance' stall ballot counts at elections offices across...

Suspicious mailers have been reported at multiple elections offices throughout Washington state, including the King County elections headquarters in Renton, which was evacuated Wednesday. Traces of fentanyl were reportedly discovered in one envelope.

“This morning, our office received a piece of mail — not a ballot envelope but a regular a piece of mail through the regular mail stream — that contained a white powdery substance in it," said King County Elections spokesperson Halei Watkins from the parking lot of the Renton headquarters. "We immediately isolated and evacuated the building ... Hazmat and law enforcement are on site.”
