Maine Attorney General Aaron Frey is among 20 Democratic Attorneys General suing the Trump administration over conditions placed on federal funds.

According to the complaints, both Secretary of Homeland Security Kristi Noem and Transportation Secretary Sean Duffy have threatened to cut off funding to states that refuse to comply with President Donald Trump’s immigration agenda.

While no federal funding is currently being withheld, California Attorney General Rob Bonta said during a news conference on Tuesday that the threat was “imminent.”

“President Donald Trump can’t use these funds as a bargaining chip as his way of ensuring states abide by his preferred policies,” Bonta added.

Department of Assistant Secretary of Homeland Security Tricia McLaughlin said in a statement that the lawsuit will not stop the Trump Administration from “restoring the rule of law.”

“Cities and states who break the law and prevent us from arresting criminal illegal aliens should not receive federal funding. The President has been clear on that,” she said.

An email message seeking comment was sent Tuesday to the Department of Transportation.

Both lawsuits say that the Trump administration is violating the U.S. Constitution by trying to dictate federal spending when Congress has that power — not the executive branch.

On April 24, states received letters from the Department of Transportation stating that they must cooperate on immigration efforts and eliminate diversity, equity and inclusion programs or risk losing funds.

New Jersey Attorney General Matthew Platkin criticized the timing of Duffy’s letter when Newark’s airport struggles with radar outages and other issues.

“I wish the administration would stop playing politics with people’s lives,” Platkin said. “I wish Secretary Duffy would do his damn job, which is to make sure planes land on time, not to direct immigration enforcement.”

Meanwhile, on Feb. 24, states received letters from the Department of Homeland Security declaring that states that “refuse to cooperate with, refuse to share information with, or even actively obstruct federal immigration enforcement reject these ideals and the history we share in common as Americans.”

“If any government entity chooses to thumb its nose at the Department of Homeland Security’s national security and public safety mission, it should not receive a single dollar of the Department’s money unless Congress has specifically required it,” Noem wrote in her letter.

Attorneys general behind the lawsuits include the following states: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, Rhode Island, Washington, Wisconsin and Vermont.

The cases are being spearheaded by California but were filed in federal court in Rhode Island, a detail that the attorneys general defended by saying they filed in “any court that is going to be fair and objective and consider our factual presentation and legal analysis.”

The lawsuits are the latest legal actions that Democratic-led states have taken against Trump since he took office earlier this year. Bonta noted that California has filed more than 20 lawsuits against the administration, while Rhode Island Attorney General Peter Neronha said his state has launched more than a dozen.

While the lawsuits have challenged policies on tariffs, federal employee firings to health care research, Trump’s focus on immigration enforcement and the mass deportation of immigrants in the United States illegally have received the most attention.

This has included the president’s promise to mass deport people to the start of a registry required for all those who are in the country illegally.

“What we’re seeing is a creeping authoritarianism,” Neronha said.
