Children from public schools in town of Chatfield, Minnesota, help U.S. President Obama get up after he posed with them for picture

Children from public schools in the town of Chatfield, Minnesota, help U.S. President Barack Obama get up after he posed with them for a picture, during his bus trip to the Midwest August 15, 2011. Obama blasted Republicans over taxes on Monday as he launched a bus tour of the U.S. Midwest to tout his job-growth strategy and distance himself from anger toward Washington that could dent his 2012 re-election hopes. Obama is traveling on a bus tour through Minnesota, Iowa and Illinois. REUTERS/Jason Reed (UNITED STATES - Tags: POLITICS EDUCATION IMAGES OF THE DAY PROFILE)
