August 13, 2012. The Obama administration is reviewing the country's ethanol policy amid calls from both political parties and the United Nations to suspend annual targets as the worst drought in 56 years spurs corn prices. Twenty-five U.S. senators, both Republicans and Democrats, asked Lisa Jackson, administrator of the Environmental Protection Agency, to halt or lower mandates on how much ethanol the country must use this year and next. The senators' Aug. 7 letter followed an Aug. 1 petition from a bipartisan coalition of 156 members of the House of Representatives.
