In mid-July, Department of Homeland Security (DHS) Secretary Janet Napolitano announced that she would be leaving DHS to become president of the University of California, and expected to leave her post in September. A former governor of Arizona, Napolitano is only the third person to lead DHS, a department created a decade ago in the wake of the 9/11 attacks. Secretary Napolitano held the job throughout President Obama’s first term.

Apparently, Napolitano’s departure will create the 15th vacancy in the department’s 45 leadership positions. This includes the directorship of Immigration and Customs Enforcement (ICE) and USCIS.  ICE Director John Morton recently announced that he would be leaving DHS at the end of July, and USCIS Director Alejandro Mayorkas recently was nominated to become DHS Deputy Secretary. Other vacancies include general counsel, privacy, legislative affairs, intelligence and analysis; those top positions are currently filled with acting officials. Rand Beer, acting DHS deputy secretary, is expected to serve as Acting Secretary until Napolitano’s permanent replacement is confirmed by the full Senate.
