Brentwood has the main post office for Washington, D.C. It was the postal mail sorting facility through which anthrax-contaminated mail addressed to two members of the U.S. Senate passed in the 2001 anthrax attacks. The Post Office is now named after Joseph Curseen Jr. and Thomas Morris Jr., who were postal workers who died after exposure to the anthrax in the incident. The 633,000 square foot facility was closed October 21, 2001, because of anthrax contamination and did not reopen until December 21, 2003.
