“#BenCarson is now leading in the polls in #Iowa. Too much #Monsanto in the #corn creates issues in the brain? #Trump #GOP,” the post read.

The retweet shunned Monsanto, which has a major presence in Iowa, with facilities in 18 different cities in the state. The company also happens to be a major GOP donor.

Trump, who reportedly holds between $15,001 and $50,000 worth of Monsanto stocks, does not support the labeling of foods made with genetically modified ingredients.

When asked by the Iowa Farm Bureau, “Do you support the use of biotechnology in food products and oppose efforts to require mandatory labeling for foods simply because they contain ingredients derived from biotechnology?” Trump allegedly responded, “Yes.”

Not only that, Modern Farmer noted that Trump, a junk food lover, does not seem to have an interest in organic food or organic farmers, and assembled an agribusiness-friendly agriculture advisory council during his presidential campaign.
