Washington (CNN) - Homeland Security Secretary Janet Napolitano announced Friday she is resigning and will be nominated to become president of the University of California system.
In an e-mail to associates, Napolitano said she will leave the Department of Homeland Security in September. While her nomination must be approved by the university's board of regents at a meeting next week, Napolitano sounded confident of the outcome.
"Departing a job and community you love is never easy, but I am passionate about educating the next generation of leaders and the University of California is like no other institution in affording such an opportunity," her e-mail said.
She graduated from the University of Santa Clara in California in 1979 as its first female valedictorian.
