The U.S. Justice Department on Thursday asked California counties to provide it with lists of all inmates in their jails who are not American citizens, as well as the crimes they have been accused or convicted of and their scheduled release dates.
The Justice Department said in a statement that its “data requests” to the counties — including Los Angeles and San Francisco counties — were “designed to assist federal immigration authorities in prioritizing the removal of illegal aliens who committed crimes after illegally entering the United States.”
The requests add another layer to the Trump administration’s already roiling turf war with California over immigration policy and state and local sanctuary laws. U.S. Immigration and Customs Enforcement agents have been swarming the region making thousands of arrests as part of President Trump’s call for mass deportations, and the Justice Department is already suing the city of Los Angeles over its sanctuary policy.
State officials have long defended California’s sanctuary policies, which generally forbid local authorities from enforcing civil immigration laws but provide for exceptions in cases involving criminal offenses. They have also criticized the administration and ICE agents for their recent arrest tactics in Southern California, including by citing figures that show that a majority of those arrested had no criminal convictions.
What immediate impact the demands would have — and whether they would spark a legal challenge from the state or counties — was not immediately clear. California Atty. Gen. Rob Bonta’s office did not immediately respond to a request for comment.

The Los Angeles County Sheriff’s Department recently resumed transferring some jail inmates to ICE for the first time in years, citing criminal exceptions to state and local sanctuary laws.
A spokesperson for L.A. County referred questions about the request to the Sheriff’s Department.
Asked about the request during a Civilian Oversight Commission meeting Thursday morning, L.A. County Sheriff Robert Luna said information about all county inmates is already publicly available on the department’s website.
“The minute you get booked, processed and you get Livescanned, that’s a national system, so agents of the federal government will know you’re in custody,” he said. “So it’s not that we’re notifying them, it’s an automatic notification based on your fingerprints.”
The Justice Department said that it hoped the counties would voluntarily comply with its requests. But if they do not, it said, it would “pursue all available means of obtaining the data, including through subpoenas or other compulsory process.”
It said that while “every illegal alien by definition violates federal law, those who go on to commit crimes after doing so show that they pose a heightened risk to our Nation’s safety and security.”
Not every noncitizen in the U.S. is in the country illegally, given that there are non-citizen permanent residents and other visa holders. However, as part of its immigration crackdown, the Trump administration has given heightened scrutiny to people in those categories, as well.
Atty. Gen. Pam Bondi, in her own statement about the requests, said that removing “criminal illegal aliens” from the country was the administration’s “highest priority.”

“I look forward to cooperating with California’s county sheriffs to accomplish our shared duty of keeping Californians and all Americans safe and secure,” Bondi said.
In May, Luna’s department transferred inmates from its jails to ICE for the first time since early 2020. Between May and June, the department handed 20 inmates over to the federal agency.
At Thursday’s oversight meeting, Luna said the department received 995 civil detainer requests from ICE in 2024, and that it did not comply with any of them, which it is not legally required to do. But he said that the department had to turn over the 20 inmates because it received federal judicial warrants from federal authorities for each of them.
He said he expected such warrants to increase, which would increase the number of inmates turned over.
“Those are legal documents signed by a judge. We cannot deny those,” he said.
Max Huntsman, the county’s inspector general, and other experts have said the Sheriff’s Department is required by federal and state law to comply with the warrants, and the process is legal under state and local sanctuary policies.
