2003 Reorganization
Congress transferred several agencies that had previously been under the aegis of the Treasury department to other departments as a consequence of the September 11, 2001 terrorist attacks. Effective January 24, 2003, the Bureau of Alcohol, Tobacco and Firearms (ATF), which had been a bureau of the Department since 1972, was extensively reorganized under the provisions of the Homeland Security Act of 2002. The law enforcement functions of ATF, including the regulation of legitimate traffic in firearms and explosives, were transferred to the Department of Justice as the Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE). The regulatory and tax collection functions of ATF related to legitimate traffic in alcohol and tobacco remained with the Treasury at its new Alcohol and Tobacco Tax and Trade Bureau (TTB).
Effective March 1, 2003, the Federal Law Enforcement Training Center, the United States Customs Service, and the United States Secret Service were transferred to the newly-created Department of Homeland Security ("DHS").
