A coalition of nearly two dozen U.S. states has filed lawsuits against the Trump administration following the termination of the $7 billion Solar for All grant program, aimed at expanding solar energy access in low-income communities.

The lawsuits, announced Thursday by California Attorney General Rob Bonta, challenge the Environmental Protection Agency's (EPA) decision to cancel the program, which was part of a broader clean energy initiative under the Biden administration. The EPA, now led by Lee Zeldin, halted the program in August after funding was cut via the One Big Beautiful Bill Act, signed by Donald Trump in July.

Arizona Attorney General Kris Mayes said the cancellation would impact 900,000 low-income households nationwide, with Arizona alone losing $156 million. "Without this program, for many Arizonans, clean energy will be out of reach," Mayes said.

Among those affected are Indigenous communities, including the Hopi Tribe, which was slated to receive $25 million to electrify homes with solar and battery systems.

One of the lawsuits seeks monetary damages and has been filed in the U.S. Court of Federal Claims, while a second suit aiming to reinstate the program is expected to be filed in Washington state federal court.

The legal action is backed by 23 Democratic attorneys general from states including California, New York, Arizona, Illinois, and Oregon, along with Washington D.C. The coalition argues the program's cancellation undermines federal commitments to climate action and energy equity.
