Bloomberg reported Tuesday that Trump's visit could signal his administration's support for allowing the year-round sale of E15 gasoline, which contains 15 percent ethanol.

Trump last fall directed the EPA to lift the current policy that prohibits E15 during the summer months, a restriction that was in place because of air pollution concerns. The current summer limit is 10 percent ethanol.

The president earlier this year rolled out a plan that would allow the year-round sale of E15.

Trump's move was celebrated in Iowa, where the economy depends heavily on corn ethanol and on federal ethanol regulations. But senators in states that depend on oil production have opposed the decision, arguing it's illegal and would hurt the fuel refining industry.

Should Trump further lift restrictions on E15, it would likely boost farmers in the Midwest who are taking the brunt of the president's trade war with China.

Beijing earlier this month announced retaliatory measures for the Trump administration raising tariffs on $200 billion worth of Chinese goods. The duties from China will target beef, honey, rice, corn, wheat flour, spinach, peas, beans, lentils, peanut oil, soybean oil, sunflower oil and other agricultural products grown in the U.S.

Trump last week announced his administration will provide $15 billion in assistance to farmers affected by the trade war and has praised them as "Patriot Farmers" for waiting out the dispute.
