President Donald Trump’s environmental regulators are advancing a proposal to block states from warning consumers about herbicides and other agricultural products in their food, according to federal documents reviewed by The Lever. Among the substances that could now go undisclosed is a widely used chemical that  some studies have linked to cancer and that Trump’s own health secretary has called a “poison.”

Last month, Trump issued an executive order mandating agencies “fully address the growing health crisis in America.” But the initiative from Republican attorneys general — which would usurp state labeling authority — is now being moved forward by Trump’s Environmental Protection Agency. The measure would declare that any label citing scientific findings not acknowledged by Trump’s EPA would “constitute misbranding.”
