Homeland Security Secretary Janet Napolitano waves as she leaves after delivering her farewell address at the National Press Club in Washington, Tuesday, Aug. 27, 2013. Napolitano said her agency’s flexibility and agility have prepared it to respond to disasters and terror attacks alike. In her farewell speech before taking over the University of California system next month, Napolitano said the department’s strengths allowed it to respond quickly and effectively to hundreds of disasters and the Boston Marathon bombing.
