President Barack Obama will hit the road again to talk about jobs and the economy, resetting the message amid a busy summer that's so far been dominated by immigration reform efforts, the IRS scandal, national security leaks and the president's trips to Europe and Africa. Obama will return to Knox College in Galesburg, Illinois on Wednesday to kick off a series of speeches about his economic plan, White House senior adviser Dan Pfeiffer wrote in an e-mail to supporters Sunday evening.
