This transcript includes the November 25, 2002 remarks of President Bush at the signing of the bill establishing the Department of Homeland Security. "Today I have signed into law H.R. 5005, the 'Homeland Security Act of 2002.' The Act restructures and strengthens the executive branch of the Federal Government to better meet the threat to our homeland posed by terrorism. In establishing a new Department of Homeland Security, the Act for the first time creates a Federal department whose primary mission will be to help prevent, protect against, and respond to acts of terrorism on our soil."
