Protesters gathered in cities across the country Saturday to protest what they call "big agribusiness" and the prevalence of genetically modified foods.
In front of the statehouse in Denver, there was a crowd of about 500 people. The rally was organized under the banner of March Against Monsanto.
Signs have slogans like "Just Say No To GMOs" and "Keep Calm and Label On."
One of the rally’s speakers, Alan Lewis, works on ag policy for Vitamin Cottage.
