Executive Order 13753
Amending the Order of Succession in the Department of Homeland Security
This executive order updates the line of succession for acting Secretary of Homeland Security, replacing a 2007 order with a new ranked list of 18 DHS officials. It specifies who assumes leadership if the Secretary dies, resigns, or becomes unable to serve, while preserving presidential discretion to depart from the list under the Federal Vacancies Reform Act.
