Des Moines Register: After months of false starts, President Donald Trump will tell Iowans today during a campaign rally in Council Bluffs that he’s opening the door to year-round access to gasoline with higher ethanol blends. A senior White House official said Monday that Trump directed the Environmental Protection Agency to begin rule-making that allows for year-round use of gasoline with 15 percent ethanol, or E15. The move should help Iowa farmers and U.S. consumers at a time when years of record harvests — and Trump trade wars with Canada, Mexico and China — have helped depress corn and soybean prices.
