Overview
- A building at the Maryland installation was evacuated Thursday after an individual opened a suspicious package, and a security cordon was established.
- Base medical teams treated multiple people who reported symptoms, with officials later saying the patients were in stable condition and released.
- The envelope contained an unknown white powder, initial HAZMAT field tests did not detect anything hazardous, and the HAZMAT team departed Thursday evening.
- The Office of Special Investigations is leading the probe, the affected room in the Air National Guard Readiness Center remains sealed, and investigators are reviewing political materials found in the package.
- Joint Base Andrews routinely supports presidential and other VIP travel, and President Donald Trump was at the base on Wednesday.
