NEW YORK — For years as an environmental lawyer, Robert F. Kennedy Jr. crusaded against a controversial herbicide ingredient known as glyphosate, even winning a landmark case against chemical giant Monsanto by arguing that its Roundup weedkiller contributed to his client's cancer.
But now that he's the nation's top health official, Kennedy is falling in line with President Donald Trump after he issued an executive order that's aimed at boosting glyphosate's production. The order would also grant limited legal immunity to manufacturers if they're following federal directives.
Kennedy on Sunday evening posted a lengthy statement on social media that calls pesticides ''toxic by design'' but frames Trump's move as necessary for agricultural stability and national security.
''President Trump did not build our current system — he inherited it,'' Kennedy wrote. ''I support President Trump's Executive Order to bring agricultural chemical production back to the United States and end our near-total reliance on adversarial nations.''
It was a gesture of loyalty to the president who has enabled Kennedy's overhaul of vaccine policy at the federal government's highest levels, but it also opens a dangerous fault line in their political coalition ahead of the midterm elections in November.
As Kennedy's Make America Healthy Again supporters grow impatient with a Republican-led administration that's largely resisted their calls to regulate pesticides, they're speaking up about what they view as a betrayal of their support.
''It's been a year. Not a single thing has been done by the EPA to reduce our children's and families exposure to pesticides,'' Moms Across America founder Zen Honeycutt, a prominent MAHA activist, replied to Kennedy's post. ''We love you Bobby but this administration needs to keep their word.''
Critics of the executive order said it is part of a pattern that favors pesticide manufacturers, who defend their products as rigorously reviewed by regulators to ensure they don't threaten human health if used properly.
