The US Federal Bureau of Investigation (FBI) has arrested 67-year-old Robin Patrick Martin of Oklahoma City, Oklahoma, who is accused of mailing more than 700 letters containing white powder and threats to hundreds of federal and state officials. The indictment was unsealed on November 3, 2026, just days before the midterm congressional elections. According to prosecutors, the defendant sent envelopes with powder to US members of Congress, election board staff, pollsters, media representatives, and law enforcement agencies.

What Was Inside the Envelopes and What Experts Say

According to investigators, Martin is charged with spreading false information that causes panic and sending threats through the postal system. Initial laboratory tests showed that the white powder was not dangerous and generally consisted of yeast or flour. However, authorities emphasized that not all received letters have been fully tested. Some of the messages were written in ink that only appears under ultraviolet light and contained warnings that the recipient could be arrested for treason or "something even worse." In one letter, as court documents show, the text read: "Get on the right side of history. Your life may depend on it."

Connection to the Electoral Process

According to statements by FBI agent David Cole recorded in the affidavit, many letters focused on claims about the integrity of US elections and warned that similar problems could recur in future election cycles. Several envelopes were sent with a fake return address under the name "Army to Destroy American Traitors." According to US authorities, this points to a targeted attempt to sow fear among civil servants and election officials during a sensitive pre-election period.

How the Suspect Was Identified

According to the FBI, the investigation began back in 2024 after election officials in several states received letters containing white powder and threatening statements. Investigators gathered surveillance footage showing the defendant mailing letters at multiple post offices in Oklahoma City, Dallas, and San Antonio. Authorities stated that identifying the suspect was also made possible through fingerprints and other forensic evidence.

Potential Penalty

If convicted, Martin faces a multi-year prison sentence under federal statutes. The case is being viewed as an example of pressure on election infrastructure and public servants ahead of the 2026 midterm elections, which investigators argue requires a firm law enforcement response.
