Tina Peters embraced conspiracy theories. Officials say she has become an insider threat.

Being told to sit through a presentation of wild, debunked claims was “a huge slap in the face,” one Mesa County elections-division employee said of the previously unreported episode. “We put so much time and effort into making sure that everything’s done accurately,” the employee told The Washington Post, speaking on the condition of anonymity out of fear of retaliation. Peters, the elected county clerk, had expressed sympathy for such theories in the past, the employee said.
