A story about unintended consequences - it begins two years ago, when lawmakers in Washington passed a massive energy bill. It was applauded by corn farmers because it contained provisions that would help boost ethanol production and in turn, drive up the price of corn. But now Ohio livestock producers are worried. They feed corn to their cattle, hogs and poultry. And at $4 a bushel on the Chicago Board of Trade, corn prices are double what they were last summer. That's squeezing some farmer's bottom lines. And that could mean higher prices for consumers. From Washington, Chad Pergram reports.
