FBI probes nationwide wave of suspicious powder mailings targeting Congress and election offices

Key points

• The FBI and US Postal Inspection Service are investigating over 100 suspicious mailings sent to congressional and election offices across at least 19 states.
• Most packages were intercepted by postal services before delivery, but some reached their destinations, including offices of Rep. Jimmy Panetta and Sen. Amy Klobuchar.
• The mailings contain an unidentified white powder, with some envelopes bearing a return address linked to the Democratic Socialists of America, which no longer uses that address.
• No hazardous substances have been confirmed in the packages, and no injuries have been reported, though officials are treating the incidents as a potential threat to election integrity.
• The incidents occur three weeks before the midterm elections, prompting heightened security measures and evacuations in several states, including California, Minnesota, and Alabama.

Background

This development follows a series of earlier reports in October 2026 detailing a nationwide pattern of suspicious powder mailings targeting political and election offices. Previous coverage highlighted incidents in Ohio, Louisiana, and Oklahoma, where packages were either intercepted or received, leading to evacuations and increased security. The current wave expands the scope of the investigation, with federal authorities now focusing on identifying the sender and preventing further deliveries as the midterm elections approach.

How outlets are covering it

The New York Post emphasizes the specific incident involving Rep. Jimmy Panetta’s office and the broader pattern of mailings linked to a DSA-associated address, highlighting the political implications and the response from California lawmakers. CBS News focuses on the impact on Minnesota officials, including Sen. Amy Klobuchar and Rep. Kelly Morrison, and notes the timing of the mailings relative to early voting. WSFA highlights the FBI’s response to the Alabama Secretary of State’s office, emphasizing the coordination between federal and state law enforcement. The sources generally agree on the scale and nature of the mailings but differ in their emphasis on specific locations and the political context, with some outlets focusing on the potential for election interference and others on the lack of confirmed hazardous substances.

Why it matters

The suspicious mailings raise concerns about the safety of election officials and the integrity of the upcoming midterm elections. The incidents have prompted heightened security measures and evacuations, potentially disrupting the work of election offices and congressional staff. The FBI’s investigation aims to identify the sender and prevent further deliveries, but the lack of confirmed hazardous substances suggests the mailings may be designed to cause fear rather than physical harm. The timing of the incidents, three weeks before the elections, adds to the urgency of the investigation and the need for robust security measures to protect the democratic process.

What to watch

The FBI and US Postal Inspection Service will continue to investigate the mailings and work to identify the sender. Federal authorities are expected to issue further updates as the investigation progresses, and security measures at congressional and election offices are likely to remain heightened in the lead-up to the midterm elections. The outcome of the investigation will determine whether the mailings are linked to a broader attempt to interfere with the elections or are isolated incidents of attention-seeking behavior.
