On January 24, 2006, Halliburton's subsidiary KBR (formerly Kellogg, Brown and Root) announced that it had been awarded a $385 million contingency contract by the Department of Homeland Security to build "temporary detention and processing facilities" or internment camps. According to Business Wire, this contract will be executed in cooperation with the U.S. Army Corps of Engineers, Fort Worth District. Critics point to the Guantanamo Bay detention camp as a possible model. According to a press release posted on the Halliburton website, "The contract, which is effective immediately, provides for establishing temporary detention and processing capabilities to augment existing Immigration and Customs Enforcement (ICE) Detention and Removal Operations (DRO) Program facilities in the event of an emergency influx of immigrants into the U.S., or to support the rapid development of new programs. The contingency support contract provides for planning and, if required, initiation of specific engineering, construction and logistics support tasks to establish, operate and maintain one or more expansion facilities."[41]
