Nearly 200 activists in Robert F. Kennedy Jr.’s “Make America Healthy Again” movement have criticized President Donald Trump’s push to use coal for AI data centers.

They sent a letter Friday to Trump, Kennedy, and other officials.

The letter objects to a 2025 executive order boosting coal and asks for renewable options like solar and geothermal energy.

The activists said American AI leadership should not come at the cost of a more toxic burden for children.

White House spokesperson Taylor Rogers responded that emissions hit a 30-year low in Trump’s first term.

He said Trump had a mandate to roll back radical climate policies.

Prominent figures behind the letter include Zen Honeycutt and Charles Eisenstein, both former Kennedy campaign staffers.

Honeycutt said she asked the MAHA Action PAC to sign on but got no reply.

The letter marks the first major MAHA mobilization over fossil fuels.

Many in the movement have grown frustrated with the administration over pesticides and environmental deregulation.

Some say they will vote on issues rather than party this fall.

The letter asks for transparent review of data center locations and power sources, and for respect of existing environmental review rules.
