schwit1 writes with news that the U.S. Secretary of Homeland Security, Janet Napolitano, has resigned her post. Napolitano entered the office at the beginning of President Obama's first term, and she was only the third person to hold the position since it was created in response to the September 11th attacks. In a statement, she said the Department of Homeland Security "has improved the safety of travelers; implemented smart steps that make our immigration system more fair and focused while deploying record resources to protect our nation's borders; worked with states to build resiliency and make our nation's emergency and disaster response capabilities more robust; and partnered with the private sector to improve our cybersecurity." Napolitano will be taking over the presidency of the University of California's 10-campus education system. "UC officials believe that her Cabinet experiences –- which include helping to lead responses to hurricanes and tornadoes and overseeing some anti-terrorism measures — will help UC administer its federal energy and nuclear weapons labs and aid its federally funded research in medicine and other areas."
