(Salem, OR) -- The State of Oregon is investigating a COVID-19 testing company with three sites in the Portland area and 300 sites across the country. Willamette Week reports the Oregon Department of Justice has confirmed the investigation. It received at least two complaints last October. One person who took a test said the company wasn't careful in how it handled the test material. The Center for Covid Control has testing sites in Northeast Portland, Southeast Portland, and Tigard. All three sites were closed on Tuesday, but the company's call center couldn't say why. The Oregon Health Authority says the company hasn't received any state funds.
