Biden unveiled his ethanol plan in Iowa. Here's what we learned during president's visit to Menlo

President Joe Biden was in Iowa on Tuesday to discuss his economic agenda and announce lifting restrictions on E15 gasoline sales to help ease fuel prices.

After a delay, Biden arrived at Des Moines International Airport on Tuesday afternoon. From there, the president traveled to Menlo, a town of fewer than 400 people about 50 miles west of Des Moines.

At a Poet ethanol plant in Menlo, Biden addressed a small crowd of Iowa’s biofuel and political leaders.

Here's what else we learned during Biden's trip to Menlo.

What did Biden say about ethanol?

The president formally announced that he will direct the U.S. Environmental Protection Agency to use an emergency waiver to allow sale of gasoline with 15% ethanol, called E15, to help boost fuel supplies over the summer. It isn’t intended to be a permanent fix.

"This industry has a role to play in a sustainable energy future," Biden said. "But I’m here because homegrown biofuels have a role to play right now — right now as we work to get prices under control and reduce the cost for families."

E15 is currently banned in some states from June 1 to Sept. 15 because is believed to contribute to smog during warmer weather. Supporters of ethanol say that is unfounded.

What did Biden say about Putin and Ukraine?

Biden's ethanol announcement came as consumer gas prices reached record highs — a situation Biden has blamed on Russia’s war with Ukraine, but which Republicans have attributed to Biden’s energy policies.

"I’m doing everything within my power by executive order to bring down prices and address the Putin price hike," he said. "... Your family budget, your ability to fill up your tank — none of it should hinge on whether a dictator declares war and commits genocide half a world away.”

Before heading back to the White House from Iowa, Biden told reporters Tuesday that he intentionally said "genocide” when describing Russia’s atrocities against Ukraine.

“It’s become clearer and clearer that Putin is trying to wipe out the idea of being Ukrainian,” Biden said.

What did Republicans say about Biden's visit?

Republican Party of Iowa chairperson Jeff Kaufmann and U.S. Sen. Joni Ernst said on a call with reporters Tuesday that the announcement is a good thing for Iowa consumers. But they said Biden should have made the change earlier, and they criticized him more widely for his handling of inflation across the country.

Ernst told reporters Tuesday that she would like to see the move to year-round E-15 become permanent and wants to see more support for biofuels in general.

Republican U.S. Sen. Chuck Grassley applauded Biden's announcement in a statement Tuesday.

“I’m glad President Biden is finally listening to what Senator Ernst and I have been saying for months," he said.
