evidence: The letters add to the challenges facing election workers, who have been besieged by threats and harassment in recent years. At a news conference Thursday, Georgia Secretary of State Brad Raffensperger (R) confirmed that his office was alerted Wednesday to a letter containing fentanyl that was sent to election offices in Fulton County, Ga. Raffensperger, who lost his son to a fentanyl overdose five years ago, called the incident "domestic terrorism." He added in a statement that his office is "working with our state and federal partners to determine if any additional Georgia officials are being targeted." Both Raffensperger and Fulton County have been the subject of former president Donald Trump’s ire in the wake of the 2020 presidential election. Raffensperger refused Trump’s demand to "find" enough votes in the state to overturn his defeat. And Trump faces federal charges brought in Fulton County alleging he participated in a criminal conspiracy to illegally overturn his 2020 loss. Trump has pleaded not guilty to the charges.
