Sen. Charles Grassley (R-Iowa) says he wants to instill some “common sense thinking” at the Environmental Protection Agency and is inviting Administrator Lisa Jackson and other agency officials to visit a farm in Iowa.  “I don’t think the people at the EPA get the big picture. And, I’m pretty sure they don’t understand how American agriculture works,” Grassley said. “I know this is the case regarding the indirect land use issue. Margo Oge, the director of the office in charge of this rule, admitted during a committee hearing in the House of Representatives last month that she’s never been on a farm in the U.S.”
