The Short Version
RFK Jr. did back Trump's executive order boosting glyphosate production, representing a shift from his prior anti-pesticide activism. However, he never publicly stated that glyphosate is "safe." In the same social media post endorsing the order, he called pesticides "toxic by design." He later called glyphosate "poison" on Joe Rogan and told MAHA supporters he disagreed with Trump's decision. The claim's core assertion — that he told supporters the herbicide is safe — is directly contradicted by his own recorded statements.
