US President Barack Obama arrives on stage to address a campaign event at the University of Illinois at Chicago in Chicago, Illinois, on January 11, 2012. Obama sought to strike an implicit contrast with his most likely general election foe Mitt Romney, imploring big businesses to bring home US jobs outsourced overseas. White House officials insist that Obama has not yet started to focus on his bid for a second term in November, but is instead concentrating every day on his job, which he sees as reviving the economy and cutting unemployment.
