FBI Investigates Suspicious Mailings Sent to Election and Congressional Offices

Federal authorities are investigating a series of suspicious mailings containing unknown substances sent to state election offices and congressional offices across the United States. While many letters were intercepted by the U.S. Postal Service before delivery, officials are urging caution as they work to identify the sender ahead of the November 3 midterm elections.

Federal Agencies Investigate Nationwide Suspicious Mailings

The FBI and the U.S. Postal Inspection Service confirmed they are investigating a series of suspicious mailings sent to various addresses nationwide. The probe includes offices of secretaries of state, related election offices, and multiple members of Congress. Federal officials have not publicly identified the substance contained within the envelopes, though reports from several states describe it as a powdery white substance. Preliminary information suggests there may be over 100 such letters currently circulating throughout the country.

Deputy Postal Inspector Brendan Donahue emphasized that authorities are dedicating full resources to the case.

Impact on Congressional and State Election Offices

The wave of suspicious mail has triggered security protocols in both Washington, D.C., and state capitals. According to a notice from the Senate Sergeant at Arms, law enforcement is working to intercept any additional letters before they are delivered, however, it is possible that some letters may reach their destinations. The House Sergeant at Arms also issued warnings, advising district offices to utilize safe mail handling procedures, including the use of specialized mail hoods that allow staff to process deliveries without direct exposure to potentially hazardous materials.

Several high-profile figures have been targeted in the ongoing operation:

• Senate Minority Leader Chuck Schumer, D-N.Y.: Federal investigators identified him as one of the intended recipients of a letter containing a suspicious substance.
• Sen. Chris Murphy, D-Conn.: His office confirmed receiving a letter; a spokesperson, Josh Sorbe, stated they were promptly informed by the FBI, the Sergeant at Arms, and Capitol Police.
• Sen. Alex Padilla, D-Calif.: His office confirmed receiving notification from the FBI that a letter was intercepted by the U.S. Postal Service before it could reach his staff.
• Sen. Lisa Blunt Rochester, D-Del.: Her office reported that a suspicious piece of mail was safely intercepted.
• Sen. Kirsten Gillibrand, D-N.Y.: An aide confirmed a letter meant for the senator was found at her New York City office and was investigated by postal inspectors.
• Louisiana Secretary of State: An employee at the Baton Rouge elections division opened a package on Tuesday, prompting an evacuation, though testing later confirmed the substance was not hazardous.
• Ohio Secretary of State: Federal investigators intercepted a package containing a white powder before it reached the state’s election office.
• Nebraska Secretary of State: Bob Evnen reported this was the second time a suspicious envelope had been delivered to his office, with the first incident occurring in 2024.

Screening Protocols Protect Officials from Hazardous Mail

The incidents coincide with the 25th anniversary of the 2001 anthrax attacks, which fundamentally changed how mail is processed on Capitol Hill. Today, mail destined for congressional offices is screened and irradiated at offsite facilities, a procedure that has helped keep the current wave of threats from reaching lawmakers directly. The Senate Sergeant at Arms warned staff that suspicious letters might exhibit multiple postage markings and should be treated as potentially hazardous.

The current situation mirrors threats seen in previous election cycles. In 2023, election offices in six states received mail containing white powder, with some samples found to contain trace amounts of fentanyl. During the 2024 election, at least 15 state election offices reported receiving similar suspicious packages. Authorities have not confirmed if the current letters are connected to those previous incidents or if they share a single origin.

In a joint statement, the National Association of Secretaries of State and the National Association of State Election Directors expressed alarm at the recurring threats. Those who administer our elections should never fear for their safety while carrying out their essential duties, the organizations stated. While the investigation remains active, federal authorities continue to urge all recipients to exercise extreme caution and follow established safety protocols when encountering unexpected mail.
