Play videoA video released in 2016 by the DHS, detailing its duties and responsibilities

In response to the September 11 attacks, President George W. Bush announced the establishment of the Office of Homeland Security (OHS) to coordinate " homeland security" efforts. The office was headed by former Pennsylvania governor Tom Ridge, who assumed the title of Assistant to the President for Homeland Security. The official announcement states:

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.[5]

Ridge began his duties as OHS director on October 8, 2001.[6] On November 25, 2002, the Homeland Security Act established the Department of Homeland Security to consolidate U.S. executive branch organizations related to "homeland security" into a single Cabinet agency. In January 2003, the office was superseded, but not replaced by the Department of Homeland Security and the White House Homeland Security Council, both of which were created by the Homeland Security Act of 2002. The Homeland Security Council, similar in nature to the National Security Council, retains a policy coordination and advisory role and is led by the assistant to the president for homeland security.[5] The Gilmore Commission, supported by much of Congress and John Bolton, helped to solidify further the need for the department. The DHS incorporated the following 22 agencies.[7]
