What was the key legal outcome for Bayer in the U.S. Supreme Court decision regarding Roundup and glyphosate?

On June 25, the U.S. Supreme Court ruled 7–2 that plaintiffs cannot sue Bayer under state law for failing to include a cancer warning label on Roundup, effectively blocking thousands of lawsuits alleging glyphosate causes cancer; this decision marked Bayer’s biggest legal win yet and led to its largest single-day stock gain in 23 years.

How has the Trump administration’s stance on pesticides diverged from public health advocates’ expectations, particularly regarding Roundup?

The Trump administration sided with Bayer in the Roundup litigation, creating a rift with pesticide opponents—including figures in Robert F. Kennedy Jr.’s 'Make America Healthy Again' movement—who had supported Trump in the 2024 election; Ken Cook of the Environmental Working Group interpreted this as the administration prioritizing ‘big farmers and pesticide companies’ over public health concerns.
