The corn is being grown in Kansas, which is a key battleground for President Donald Trump.
The Corn Refiners Association says the corn is grown in the Kansas Corn Refinery’s “Big Bend” area, but there are no official numbers available.
The Associated Press also asked for confirmation but the association said it has no records on the crop.
Corn is a staple crop in Iowa, Nebraska and the Dakotas.
The Iowa Corn Growers Association says it has confirmed its own corn is in Big Bend.
