The MAHA coalition expected a friendly EPA. On glyphosate, they got the same institutional inertia every previous administration delivered. When prominent Make America Healthy Again figures rallied outside the Supreme Court in April 2026, lobbing criticism at Trump's own regulatory agency for siding with a pesticide maker, the scene was hard to misread: a president's health-aligned base openly breaking with his apparatus. But this fracture has a history older than any one administration. The corporate strategy that kept glyphosate's risks out of mainstream conversation for decades was built memo by memo, and one journalist traced its construction before most people were paying attention.

Following the current MAHA anger means holding several constraints in view at once. The Supreme Court case turns on preemption: whether federal pesticide labeling rules block state-level failure-to-warn claims. That is a legal question with enormous practical stakes, but it is separate from the toxicological question of whether glyphosate causes cancer. Both sit alongside a political constraint that makes this moment unusual. The MAHA movement anticipated a sympathetic EPA, only to discover that the agency's institutional relationship with Monsanto's successor company, Bayer, persists regardless of who occupies the White House. You can follow the courtroom arguments, the protest footage, and the Farm Bill amendments in real time. What you cannot reconstruct from headlines is how the information environment around glyphosate was shaped long before any of these actors arrived.

Carey Gillam's Whitewash is the product of years spent covering the agrochemical industry, and its central contribution is documentary. Gillam obtained internal Monsanto communications, including memos, emails, and strategic planning documents, that show how company teams organized campaigns to discredit independent studies linking glyphosate to cancers and endocrine disruption. These are corporate records showing specific employees coordinating specific responses to specific findings, the kind of paper trail that turns suspicion into evidence.

The book traces glyphosate's trajectory from a promising herbicidal compound to the most widely applied weed killer on Earth, sprayed across millions of acres of farmland, suburban lawns, school grounds, and public parks. Gillam documents how Monsanto marketed Roundup as essentially benign while independent research was producing results that contradicted that safety narrative. She places what researchers found against the public claims made by both the company and regulators who relied on industry-funded data.

Where the book earns its relevance to 2026 is in reconstructing how relationships between corporate scientists and regulatory officials eroded the boundary between oversight and collaboration. Gillam details episodes where EPA staff communicated with Monsanto in ways that, at minimum, suggest the agency's independence was compromised. This is the material that connects to the MAHA frustration: institutional capture did not begin with any recent appointee, and replacing one will not fix it. A fair criticism: Gillam's investigative focus on Monsanto sometimes narrows the frame too far. Glyphosate's regulatory story involves the EPA, the WHO's International Agency for Research on Cancer, the European Food Safety Authority, and dozens of national regulators with conflicting conclusions. Whitewash gives IARC's 2015 classification of glyphosate as "probably carcinogenic" significant weight without spending equal time on the methodological criticisms that other scientific bodies raised about that assessment. The book works as an account of corporate manipulation of science. As a balanced toxicological survey, it has gaps, and those gaps matter because the people arguing about glyphosate in 2026 are not all arguing about the same thing. Some want a full ban based on the precautionary principle. Some want better independent testing. Some want to know whether the cereal they feed their kids is safe. Whitewash speaks most directly to the middle group: people trying to understand why the information they have received about this chemical has been so aggressively managed, and by whom.

The MAHA coalition's anger at the EPA is new. The conditions that produced it are decades old. Gillam reported this story before it had a political coalition attached to it, which gives Whitewash a clarity that post-hoc accounts will struggle to match. Given the Supreme Court docket and the ongoing Farm Bill debates over pesticide labeling, glyphosate is staying in the conversation. This book supplies the institutional history that the current debate keeps assuming but rarely delivers.
