JOHNSTON — With the clock ticking on making changes to a proposed federal renewable fuel rule, Iowa biofuels industry leaders turned up the pressure Wednesday on making the Trump administration live up to the president’s own promise.The industry leaders say they expect President Donald Trump to honor the deal his office struck with them on the federal ethanol mandate, and to reject a proposal unveiled Tuesday by Trump’s Environmental Protection Agency.“No more Iowa nice,” said Iowa Corn Growers Association Chief Executive Office Craig Floss during a news conference Wednesday, in relaying a message given him by a farmer.
