That's not at all what the Summit County article says. What it says is that the machines automatically generate a certificate (with a signature), and the person whose signature is on the cert hasn't been the one testing them since 2015. The state has been presenting these as their sole evidence of accuracy despite knowing that they were improper and then later backtracking and denying that the certificates had anything to do with the accuracy at all--a strange position to take. "The agency has said that the presence of the signatures was not intended to show whether or not the machine was properly calibrated."

But this is the best quote from the article, "The office of Governor John Hickenlooper has said an internal investigation turned up no evidence of wrongdoing at CDPHE."  In the least shocking result of all time, an internal investigation of government employees by government employees has turned up no wrongdoing. Also, sun sets in the west.
