A wave of suspicious mailings has impacted political and election infrastructure across the United States. According to reports, more than 36 congressional offices and various election administration buildings in at least 32 states have been targeted with letters containing a powdery substance.

One recent incident involved the district office of Representative Adam Smith (D-Wash.), which was evacuated on Monday after staff discovered a letter containing a suspicious powder. These events have caused significant operational disruptions, forcing temporary closures and evacuations at a time when election offices are under high pressure due to the approaching 2026 midterm elections.

While the substance in these letters is currently being investigated, the pattern of the mailings has prompted widespread concern among officials. Law enforcement and postal authorities are working to determine the origin of the letters and whether they are part of a coordinated effort to intimidate public servants and disrupt the electoral process. As of now, authorities have not confirmed the nature of the powder or identified a specific suspect, but the scale of the distribution—spanning dozens of states—suggests a systematic attempt to create fear and logistical chaos within government and election-related facilities.
