Washington – The Federal Bureau of Investigation and the U.S. Postal Inspection Service have opened a joint investigation into a series of suspicious mailings sent to congressional offices on Capitol Hill and election offices across the country. Each envelope bore a return address for the Democratic Socialists of America (DSA) headquarters in New York City, though officials say there is no evidence linking the organization to the letters.
Letters contained unknown white powder
According to an internal email obtained by Fox 5, the letters contained a “white powder substance” of unknown composition. The FBI spokesperson described the mailings as “potentially hazardous” and emphasized that all suspicious packages should be treated with caution until fully analyzed.
Law‑enforcement response
“Some of the letters contained an unknown substance and we are working closely with our law‑enforcement partners to respond to each incident,” the spokesperson said. “We are also working with our partners to identify the individual or individuals responsible for the letters. This FBI will continue to safeguard the public and secure elections for American citizens.”
An email from the U.S. Senate Sergeant at Arms warned that officials are attempting to intercept additional letters before delivery, but some may still reach their destinations. The notice included an image of an envelope with the DSA return address in the top‑left corner.
Historical context
The mailings arrive just days before the 25‑year anniversary of the 2001 anthrax incident in which a staffer in then‑Senate Majority Leader Tom Daschle’s office opened a letter laced with anthrax spores. The timing also coincides with the upcoming midterm elections, which will determine control of Congress.
Expert commentary
Robert McDonald, a retired FBI special agent who served at the White House during the 2001 anthrax attacks, explained that investigators will examine the envelopes, any residues, and even the writing instruments used. “A wide array, if you will, of people who do this type of thing for different reasons,” McDonald said. “The investigation’s now going to key in on that, and we’re also going to see if anything was put on social media.”
Former U.S. Capitol Police Chief Steven Sund added that standard mail‑screening protocols are designed to address such threats. “They’re going to do a long history of analyzing both the envelope, the contents, the writing, and everything surrounding it, so there’s going to be significant evaluation and research done,” Sund said. “I’d be surprised if they don’t identify who the suspect is.”
Congressional reaction
Rep. James Walkinshaw (D‑Va.) directed his staff to take precautions, noting that similar incidents have occurred in the past. “We’ve had this situation before in our history with white powdery dangerous substances being mailed to congressional offices and others around the country,” Walkinshaw said. “It’s really concerning, and it reflects the heightened partisanship we’re seeing across the nation.”
While the investigation remains ongoing, officials have not disclosed whether the substances pose an immediate threat to health or safety. The FBI and Postal Inspection Service continue to work with local law‑enforcement agencies to locate the source of the letters and ensure the security of election infrastructure.
What voters should know
Election officials across the United States have been advised to remain vigilant, follow established hazardous‑mail protocols, and report any suspicious packages to authorities. The public is urged not to handle unknown substances and to contact local law‑enforcement if they receive any mail that appears unusual.
