An envelope containing fentanyl was mailed to an elections office in northern California, where a worker was exposed to the drug, officials said on Wednesday.
The elections department in Yuba county, a rural area about 40 miles from Sacramento, the state capital, received the package on Tuesday. It appeared to come from a “verified agency” and did not initially look suspicious, a county spokesperson said. A staff member found a powdery substance inside and contacted law enforcement.
