What We Know About Suspicious Letters Sent to Election Offices

Election offices in at least 32 states received suspicious letters in the two weeks before the 2026 midterms, and some of those letters contained white powder, according to a WIRED investigation discussed on the outlet's Uncanny Valley podcast. The finding was outlined on the Oct. 22 episode by Leah Feiger, WIRED's director of politics and science, alongside executive editor Brian Barrett, according to the show's published transcript.

What did WIRED's investigation document before the midterms?

The episode notes describe a wave of suspicious mail reaching election administrators nationwide, timed roughly two weeks ahead of the midterm vote. Some envelopes reportedly contained white powder, a substance historically used in hoax mailings meant to trigger evacuations or law-enforcement response. The transcript does not state whether lab testing confirmed the powder in these letters was hazardous, and no additional detail on that point appears in the source material reviewed for this report.

How many states and offices were affected?

WIRED's reporting, referenced in the episode under the article title "Election Offices in at Least 32 States Have Received Suspicious Letters," puts the number of affected states at a minimum of 32. The podcast discussion does not specify an exact count of individual election offices, a breakdown by state, or a running total as the investigation continued. Those figures were not included in the source material made available for this article.

Who sent the letters, and what remains unconfirmed?

The episode does not name a suspect, identify a motive, or link the mailings to a specific individual or group. It also does not confirm whether any letter has been tied to prior harassment campaigns against election workers, a concern that has recurred in past election cycles. Feiger said on the episode that she and Barrett would "talk through what happened and how election officials are responding," but the transcript excerpt provided does not detail specific statements from named election officials, arrests, or a law-enforcement timeline. Those gaps mean readers should treat the scope and origin of the campaign as still developing rather than settled.

How did WIRED frame the story alongside other coverage that week?

The suspicious-letters segment was one of three topics on the Oct. 22 episode, which also featured WIRED global editorial director Katie Drummond discussing her interview with filmmaker Nathan Fielder about his documentary You Can See Everything, kept confidential ahead of publication. The hosts separately discussed recent pledges from technology executives: Anthropic said it would commit 5 percent of company shares to a public benefit fund, and Elon Musk said he would give one SpaceX share to every child in America. Barrett and Feiger said on the episode that they would discuss "the motivations behind these pledges and the chances that they'll actually happen," language that treats both commitments as unverified promises rather than completed transfers. No implementation timeline, eligibility criteria, or legal structure for either pledge was detailed in the source material.

What terms are useful for understanding this story?

Public benefit fund — A pool of company shares or assets earmarked for a stated public purpose rather than private shareholder return; the exact governance of Anthropic's fund was not specified in the episode.

White powder letter — A piece of mail containing a powdery substance, often used historically as a hoax to simulate a biological or chemical threat and prompt an emergency response; whether the substance in these letters was tested or identified was not stated in the source material.

Midterms — U.S. congressional and state elections held two years into a presidential term; the letters described arrived roughly two weeks before the 2026 midterm vote.

Uncanny Valley — WIRED's weekly podcast on technology and policy, hosted by Brian Barrett and Leah Feiger, where the Nathan Fielder interview and election-letters reporting were discussed on the Oct. 22 episode.
