U-S Senator Ron Johnson says changes to the nation’s food stamp program are aimed at making parents more self-reliant.  Johnson attended a town hall-style meeting at SourceCut Industries in Osseo Wednesday afternoon.  The Wisconsin Republican says changes made to the farm bill are based on focusing government assistance to those who are truly needy.  He says six percent of the American population is on food stamps during a good economy historically.  The latest statistics find more than 13 percent are accepting SNAP benefits now.  Johnson says he thinks “something is a little haywire.”
