11 JUNE 2019 - COUNCIL BLUFFS, IOWA: US President DONALD J. TRUMP talks to Iowa and Nebraska farmers and biofuel industry representatives at Southwest Iowa Renewable Energy. President Trump visited Southwest Iowa Renewable Energy in Council Bluffs Tuesday to announce that his administration was relaxing rules on E15, an ethanol additive for gasoline.
