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

The FBI, U.S. Postal Inspection Service, and U.S. Capitol Police are investigating letters containing suspicious substances mailed to congressional and election offices across the United States approximately three weeks before the midterm elections. The Oklahoma State Election Board received a suspicious white powder envelope, prompting an evacuation. No injuries were reported. Election and Secretary of State organizations jointly condemned the threats, and federal authorities continue working to intercept additional letters.
