This is proposed legislation from President Bush on creating a new Cabinet Department of Homeland Security. The proposal requires an extensive reorganization of the federal government to create a single department whose primary mission is to secure the homeland by preventing terrorist attacks within the United States, reducing America's vulnerability to terrorism, and minimizing the damage and increasing recovery from attacks that may occur. The Department of Homeland Security would be comprised of four main divisions: Border and Transportation Security; Emergency Preparedness and Response; Chemical, Biological, Radiological and Nuclear Countermeasures; and Information Analysis and Infrastructure Protection. President Bush gives details about each division as well as other supporting components, interagency coordination, and lessons that history teaches about new challenges.
