Surprising news this morning. Secretary of Homeland Security Janet Napolitano, one of the longest serving members of the President's Cabinet, announced this morning that she is resigning as of early September to accept a position as the head of the University of California system. No word yet on replacements. Conceivably, this could make it a little easier to negotiate an immigration reform bill as Secretary Napolitano has - unfairly in my view - been labeled as soft on immigration enforcement and has been the frequent target of criticism from Republicans.
