Iowa Senator Joni Ernst says the oil industry is already trying to undercut the president’s move toward year-round sales of gas with a higher blend of ethanol.

President Trump this week directed the E-P-A to redraft rules so E-15 may be used during the summertime in any vehicle, not just so-called “flexible fuel” vehicles. Ernst says it is a major change

Current Clean Air Act rules prevent the sale of E-15 in much of the country from June 1st to September 15th. The Senate’s number two Republican and 19 other senators from oil-producing states sent President Trump a letter last week, saying E-15 would harm consumers who drive vehicles that are “not compatible with higher ethanol-blended gasoline.”
