WASHINGTON (AP) - The Transportation Department says former Charlotte, N.C., Mayor Anthony Foxx has been sworn in as President Barack Obama's new transportation secretary. Foxx was sworn in during a private ceremony with his wife and two children Tuesday at the department's headquarters. The department says he's spending his first day focusing on transportation safety and preparedness for hurricanes and severe weather. Foxx says under his tenure, safety will remain the department's top priority. He says he'll work on efficiency and infrastructure needed to make sure the nation's transportation system works for future generations. Foxx's background includes stints as a Justice Department attorney and a Democratic aide to the House Judiciary Committee. The Senate voted unanimously last week to confirm Foxx. The 42-year-old replaces outgoing secretary Ray LaHood, a former Republican congressman.
