USPIS Deploys Armed and Unarmed Guards to Postal Facilities Ahead of Colorado Ballot Mailings

The United States Postal Inspection Service (USPIS), the law-enforcement arm of the United States Postal Service, has begun placing armed and unarmed security guards at key postal facilities across the nation, including sites in Denver. The rollout follows a memo circulated to American Postal Workers Union members that outlines guard duties such as monitoring entrances and parking areas, verifying identification, and reporting suspicious activity. The guards will not make arrests, handle mail, supervise employees, or conduct investigations. The timing coincides with the period leading up to the distribution of mail-in ballots in Colorado—less than a week after the U.S. Supreme Court blocked portions of the Trump administration’s mail-in voting restrictions and less than two weeks before ballots are slated to reach voters’ mailboxes.

USPIS officials describe the deployment as part of a multi-year strategy to strengthen security at postal facilities, not a reaction to any specific threat or incident. A spokesperson for the USPIS Denver Division emphasized that the guards are intended to deter criminal activity or internal attempts to compromise the mailstream and to protect personnel inside the facilities. The agency directed inquiries about the broader security plan to the federal records-request process, citing operational security concerns.

Colorado elected officials have voiced suspicion about the deployment’s proximity to the upcoming election. Recorder Paul López called the guards “highly suspicious,” stressing that postal workers are public servants who should not feel intimidated while delivering election-related mail. Attorney General Phil Weiser, the Democratic nominee for governor, is scheduled to post on September 18, 2026 that the timing is “suspicious” and a “cause for concern.” U.S. Senator Michael Bennet also used social media to request an explanation from the USPS regarding the guard placements.

• “Postal workers are our allies. They are folks that are also public servants, and these are folks that do not need to be intimidated or anybody, you know, getting in their way as they're delivering mail, and that includes our elections mail as well too,” — Recorder Paul López
