In case you wondered what the Bernie Sanders (VT) amendment on GMO that failed to pass the Senate was about, here it is:

Co-sponsored by Sens. Barbara Boxer (D-Calif.) and Mark Begich (D-Alaska), Sanders’ amendment would have made clear that states have the authority to require the labeling of foods produced through genetic engineering.
In the United States, Sanders said, food labels already must list more than 3,000 ingredients ranging from high-fructose corn syrup to trans-fats. Unlike 49 countries around the world, however, foods that contain genetically engineered ingredients do not have to be labeled in the U.S.
The measure also would have required the Food and Drug Administration and the U.S. Department of Agriculture to report to Congress within two years on the percentage of food and beverages in the United States that contain genetically engineered ingredients.
