Obama to use farewell address to burnish legacy, look ahead

By Jeff Mason WASHINGTON (Reuters) - President Barack Obama will give a farewell speech to the nation on Tuesday in an effort to burnish his legacy, encourage demoralized supporters and prod the incoming Trump administration to keep some of his signature achievements in place. Obama will deliver the speech at 8 p.m. CST (0200 GMT Wednesday) in Chicago, where he kicked off his political career and started a family.
