Trump's ethanol plan: Hype now, legal fights later

According to Reuters, President Donald Trump’s hyping of a plan to boost ethanol demand drew cheers at an Iowa rally on Tuesday, but the oil refining industry has promised a lawsuit to block the move, so victory for Midwest farmers is far from certain.
President Trump indicated that the U.S. Environmental Protection Agency should allow for a waiver for higher-ethanol gasoline, known as E15, to be sold all year, which has been prohibited due to smog concerns.
