Schumer demanded the FDA release what it's found in investigations of the chemical glyphosate.

New York Senator Chuck Schumer is accusing the FDA of withholding information on an ingredient in the weed killer Roundup.

Schumer demanded the FDA release what it's found in investigations of the chemical glyphosate.

The environmental activist group, The Environmental Working Group, says glyphosate causes cancer and that it has found traces of it in oat cereals, oatmeal, and granola bars across the country.

Separate reports from the Environmental Protection Agency and the UN have found there's no indication glyphosate causes cancer.
