Federal Authorities Investigate Suspicious Substance Letters Sent to Congressional and Election Offices Nationwide

Federal authorities are investigating suspicious substance letters mailed to congressional and election offices across the United States. The Senate Sergeant at Arms notified the Senate of the investigation. Evacuations occurred at election offices in Louisiana and Oklahoma, while Ohio reported an intercepted package containing white powder. The incidents occurred approximately three weeks before Election Day, drawing comparisons to a 2023 incident involving fentanyl. National election associations issued a joint statement condemning the threats.
