U.S. Senator Chuck Grassley is joining Governor Terry Branstad and U.S Representative Steve King in speaking out against the federal government's proposal to reduce the amount of ethanol blended into gasoline next year. The politicians are leading a group of industry executives in an event this morning in Nevada aimed at defending the current levels of ethanol and biodiesel in the nation's fuel supply. The Environmental Protection Agency proposes to reduce by almost 3 billion gallons the amounts of biofuels blended into gasoline in 2014 than the law requires. Branstad says the reduction negatively impacts thousands of jobs in Iowa, the leading ethanol producer and top grower of corn, which is used in most of the nation's ethanol.
