Office of Homeland Security

On October 8, 2001, in response to the September 11, 2001 attacks, President George W. Bush announced the establishment of an executive-level Office of Homeland Security to coordinate "homeland security" efforts, to be headed by Governor Tom Ridge with the title of Assistant to the President for Homeland Security.

The official announcement stated:

The mission of the Office will be to develop and coordinate the implementation of a comprehensive national strategy to secure the United States from terrorist threats or attacks. The Office will coordinate the executive branch's efforts to detect, prepare for, prevent, protect against, respond to, and recover from terrorist attacks within the United States.

On March 12, the Department of Homeland Security Advisory System was created as a Presidential Directive to provide a "comprehensive and effective means to disseminate information regarding the risk of terrorist acts to Federal, State, and local authorities and to the American people."

In January 2003, the office was superseded, but not replaced by the United States Department of Homeland Security. The Office retains an advisory role.
