Thirteen attorneys general, including Maine’s Aaron Frey, announced their intention to file a lawsuit aimed at preventing access to national payment systems by Elon Musk and his team.

In the past week, Musk’s unofficial advisory group, called the Department of Government Efficiency, gained access to the U.S. Department of the Treasury’s payment systems, which contain the personally identifiable information of millions of Americans.

“This level of access for unauthorized individuals is unlawful, unprecedented and unacceptable,” the group said in a written statement. “DOGE has no authority to access this information, which they explicitly sought in order to block critical payments that millions of Americans rely on —payments that support health care, childcare and other essential programs.”

They charged that President Donald Trump does not have the power to cut federal payments approved by Congress or to release personal information of his choosing.

Trump has granted Musk, who is classified as a White House temporary employee, broad authority to pursue cost-cutting measures. Musk has described his team as a “wood chipper for bureaucracy” and vowed to eliminate entire agencies, and members of his team have reportedly questioned career government officials.

Musk’s actions have drawn criticism from the entire Maine delegation, including Republican Sen. Susan Collins, who chairs the Senate Appropriations Committee, which oversees discretional government spending.

The statement from the attorneys general did not specify details of the lawsuit “to stop this injustice,” including a timeline or the exact target,

Frey was joined by counterparts in Vermont, Rhode Island, New York, California and other states.

Thousands of Americans across the country demonstrated outside their state capitols Wednesday. In Maine, protesters decried Trump’s flurry of executive orders as well as Musk’s access to sensitive records.
