FBI and USPS are investigating suspicious mailings targeting congressional and election offices, with some containing unknown substances. The investigation follows a 25th anniversary of the 2001 anthrax attacks on Capitol Hill.
The investigation involves letters containing suspicious substances sent to multiple addresses nationwide, including congressional offices and election offices. Some letters contained powdery white substances, leading to evacuations in Louisiana and Oklahoma.
Authorities warn of potential threats to election officials, urging recipients to treat mailings as potentially hazardous. The National Association of Secretaries of State and the National Association of State Election Directors condemned the threats against election staff.
The investigation is ongoing, with law enforcement working to intercept additional letters before they reach their destinations. The FBI and USPS are collaborating to identify the individuals responsible for the mailings.
