President Donald Trump issued an executive order to promote domestic production of the herbicide glyphosate, the most widely used herbicide in the US for many crops and the active ingredient in Roundup.[1][3] Glyphosate faces multiple lawsuits accusing it of causing cancer.[1] HHS Secretary Robert F. Kennedy Jr., a leader of the Make America Healthy Again (MAHA) movement, supported the order on the grounds that it protects national security, defense readiness, and the food supply.[2][3] Kennedy stated that the US has 4% of the world's population, but uses 25% of the world's pesticides, and dependence on foreign producers is a security risk.[3] Supporters of MAHA, including activists such as Zen Honeycutt and Kelly Ryerson, called this move a betrayal and criticized the protection of chemical manufacturers.[1][2][3][5] The MAHA Commission issued a report in May 2025 that highlighted concerns about glyphosate in relation to chronic diseases.[4][5] Kennedy added that HHS will work to reduce reliance on glyphosate without disrupting the food supply.[3]
