NEW YORK (AP) — Nearly 200 activists in Health Secretary Robert F. Kennedy Jr.‘s “Make America Healthy Again” movement are criticizing President Donald Trump’s promotion of coal to fuel the rise of artificial intelligence data centers, according to a letter sent Friday.

The letter, signed by at least two former staffers from Kennedy’s 2024 presidential campaign, marks the first major MAHA movement mobilization over fossil fuels and the latest in a series of rifts between the diverse group of activists and the Trump administration over environmental policy.
