On October 16, local time, attorneys general of more than a dozen U.S. states sued the Trump administration, accusing it of terminating $7 billion in funding for affordable solar projects across the U.S. They claimed in the lawsuit that the U.S. Environmental Protection Agency's cancellation of the "Solar for All" program violated the laws governing federal agencies and the constitutional separation of powers.

It is reported that the state attorneys general participating in the lawsuit include California, Colorado, Connecticut, the District of Columbia, Hawaii, Illinois, Massachusetts, Maine, Maryland, Michigan, New Jersey, New Mexico, New York, North Carolina, Oregon, Rhode Island and Vermont.

Launched by former US President Joe Biden in 2022, the Solar for All program aims to provide nearly one million Americans with access to renewable energy. A month after US President Trump's massive tax and spending bill passed Congress, the EPA rescinded funding for Solar for All in August, with EPA Administrator Zeldin calling the program a "waste of money." Earlier this month, nonprofits and other groups filed a lawsuit challenging Solar for All's funding, citing similar grounds. This week, more than two dozen Democratic senators also wrote to Zeldin, calling for the program's reinstatement.
