NAACP Washington Bureau Director Hilary Shelton said Monday the envelope contained a smaller envelope with powdery material.
The business-sized envelope had no return address and was simply addressed to the civil rights organization’s office in downtown Washington.
NAACP employees called the police and left their offices. Shelton said law enforcement officials inspected the material and told him it was tea.
In October and November 2001, five people were killed after coming in contact with mailings containing anthrax.
