President Trump is taking to a stage in the Midwest with a rally in Iowa Tuesday night. Iowa has four seats in the House up for grabs and an open spot for governor, which is currently occupied by Kim Reynolds, who took over for Terry Branstad when he agreed to be Trump's ambassador to China.

Trump is expected to drum up support for a new ethanol plan to support farmers and fuel refiners throughout the country. Iowa's No. 1 export, according to the U.S. Census Bureau, is corn.
