"Supreme Court Grills Monsanto On Roundup Cancer Warning"

"Outside the court, hundreds gathered to protest the company and the Trump administration."

"Supreme Court justices on Monday appeared skeptical of Monsanto’s argument that federal law prevents state courts from holding the company financially responsible for failing to warn consumers about the risk of cancer from its popular Roundup weedkiller.

During oral arguments, Monsanto and the Trump administration faced questions about their position that EPA should have the final say on what warnings pesticides and herbicides can carry — even in light of new information about a product’s potential hazards.

Chief Justice John Roberts asked Paul Clement, the attorney representing Monsanto, why states couldn’t also hold chemical manufacturers’ feet to the fire when they’ve made a determination that a product poses risk to their residents."
