Homeland Security Act

Enacted: 2002

Signed into law by

George W. Bush

In brief

Created the Department of Homeland Security by consolidating 22 federal agencies — the largest federal reorganization since the National Security Act of 1947.

The Act in depth

Signed by George W. Bush on November 25, 2002, the Homeland Security Act combined the Coast Guard, Secret Service, Immigration and Naturalization Service, Customs Service, Federal Emergency Management Agency, and eighteen other agencies into a new Department of Homeland Security. The reorganization aimed to eliminate the intelligence 'stovepipes' that the 9/11 Commission would later identify as contributing to the failure to prevent the attacks. DHS is now the third-largest federal department by employee count.
