The Trump administration is spending large sums of federal cash to investigate a widely used herbicide that top international health organizations and scientists have already concluded causes cancer.

EPA, which is empowered to restrict or ban glyphosate — sold under the brand name Roundup, is in the midst of its own court-ordered reassessment of the herbicide. The agency hasn’t shown it’s inclined to depart from its longstanding position that the weedkiller isn’t a carcinogen.
