The NCGA, which says it represents 40,000 corn farmers, said in a tweet to Anheuser-Busch that "America's corn farmers are disappointed in you" and thanked MillerCoors for "supporting our industry."

Anheuser-Busch quickly responded that the commercial only sought to "point out a key difference" between Bud Light and its competitors and "provide consumers transparency and elevate the beer category," AP reports.
