A coalition of 24 states and Washington, D.C., is suing the Trump administration, claiming that it unlawfully dismantled the AmeriCorps grant program, an independent federal agency that funds volunteer efforts throughout the United States. The lawsuit came in response to billionaire Elon Musk’s so-called Department of Government Efficiency (DOGE) cutting the agency’s funding by $400 million and terminating about 85% of its workforce as part of the administration’s ongoing efforts to gut the federal bureaucracy.

States joining the filing include California, Colorado, Illinois, Massachusetts, New York, New Jersey, and Michigan.

In the 69-page complaint, the state attorneys general state that the administration’s stripping of resources is an “unlawful effort to dismantle AmeriCorps” that usurps the power of the legislative branch by rendering the agency ineffective and unable to pursue the goals set forth and funded by Congress.

“The Administration’s abrupt decision to dismantle AmeriCorps flouts Congress’s creation of AmeriCorps and assignment of agency duties; usurps Congress’s power of the purse and thereby violates the Constitution’s separation of powers; and arbitrarily and capriciously — without any reasoned analysis — vitiates the agency’s ability to function consistent with its statutory mission and purpose,” the 69-page complaint states. “It also violates a provision of AmeriCorps’ statutory appropriation that requires the agency to make ‘significant changes to program requirements, service delivery or policy only through public notice and comment rulemaking.’”

The suit asserts that if the Trump administration wants to put an end to the agency, it is “free to ask Congress” to do so, but the executive branch “cannot simply terminate the agency’s functions by fiat or defund the agency in defiance of administrative procedures, Congressional appropriations, and the Constitutional separation of powers.”

“The Executive Branch violates the Take Care Clause where it declines to execute or otherwise undermines statutes enacted by Congress and signed into law or duly promulgated regulations implementing such statutes,” the attorneys general wrote, adding, “The President is without authority to set aside congressional legislation by executive order.”

California Attorney General Rob Bonta said that Trump and Musk’s actions in “turning away tens of thousands of volunteers who want to serve their communities” were “unlawful,” in a news briefing on the lawsuit Tuesday afternoon.
