President Trump visits Iowa

COUNCIL BLUFFS, Iowa -- President Donald Trump returned to western Iowa for a rally Tuesday, October 9.

The rally happened at 6:30 p.m. at the Mid-America Center in  Council Bluffs.

At the rally, the president announced year-round access to E-15, which is gas with 15-percent ethanol.

Currently, the fuel is banned during summer months, due to smog concerns, but advocates argue that it's safe to use all year.

According to a report by Popular Mechanics, E-15 isn't a fuel that's good for all engines equally.  The report outlines answers to frequently asked questions relating to the compatibility for cars and other engines.

This was President Trump's fourth visit to Iowa since he was elected president.
