There's a call for a federal ban on a chemical food additive that's also used to make yoga mats and the soles of shoes.
Senator Chuck Schumer, with a cheeseburger in hand stood in front of a Manhattan McDonald’s and demanded food companies stop using Azodicarbonamide.
The chemical is used by many fast food chains to bleach their bread dough and to make it more elastic.
The Senator says studies link the chemical to cancer.
Schumer added McDonald’s isn't the only company using it in food.
