RFK Jr.’s War on Pesticides Riles Farmers and a Republican Senator

Health Secretary Robert F. Kennedy Jr.’s long-running crusade against agricultural chemicals ran into pushback on Tuesday from the agriculture industry and a Republican senator, who pointedly instructed Mr. Kennedy not to interfere with the livelihood of American farmers by suggesting certain pesticides are unsafe.

The admonition from the senator, Cindy Hyde-Smith of Mississippi, came as President Trump was preparing to release a report on Thursday from a commission, led by Mr. Kennedy and named for his movement, to examine the causes of childhood chronic disease.

Mr. Trump established the panel to look at a range of potential factors, including chemicals, which Mr. Kennedy has said “pollute our bodies the same way that they pollute the soil.” Mr. Kennedy and his followers in the “Make America Healthy Again” movement have previously singled out the agricultural chemical glyphosate, originally made by Monsanto, which is now owned by Bayer, the German chemical and pharmaceutical giant.

The key ingredient in Roundup, the chemical has long been a target of environmental groups. In 2020, Bayer paid more than $10 billion to settle tens of thousands of claims alleging Roundup causes cancer. In 2018, when he was an environmental lawyer, Mr. Kennedy helped win a $289 million judgment against Monsanto, in a case brought by a man who said the company’s weedkillers, including Roundup, caused his cancer.

As Mr. Kennedy was testifying Tuesday before members of the Senate Appropriations Committee, Ms. Hyde-Smith asserted that “1,500 studies and 50-plus years of review” of glyphosate by the Environmental Protection Agency and “other global health authorities have affirmed its safety when used as directed.” She also suggested in no uncertain terms that the commission had better get its facts straight.

“Mr. Secretary, we have to get this right; you have to be 100 percent certain,” Ms. Hyde-Smith said, adding, “Before you start suggesting an initial assessment that the methods in which the farmers provide our food is unsafe, I trust your report will be described as an initial assessment of things to be considered but yet to be determined.”
