President Donald Trump issued executive orders to crack down on illegal immigration.

One post on X said the DEA assisted the U.S. Department of Homeland Security and other federal law enforcement partners with the efforts and that agents “conducted enhanced targeted operations throughout L.A.”

U.S. Immigration and Customs Enforcement defines “targeted enforcement operations” as “planned arrests of known criminal aliens who threaten national security or public safety.”

It is unknown where exactly the L.A. raids took place or the number of people arrested, if any.

A spokesperson for the DEA said Monday she was not authorized to provide additional details beyond what the agency had already shared on social media.

ICE did not respond to a request for more information.

Immigrant rights groups have been preparing for massive crackdowns by the Trump administration since his reelection in November.

On Friday, the Coalition for Humane Immigrant Rights announced that it, along with other immigrant, labor, faith-based and community groups, had launched the Los Angeles Rapid Response Network to respond to ICE enforcement activities in the Greater L.A. area.

The network has set up a national hotline, at 888-624-4752, where callers can report immigration enforcement activities. Once alerted, the network will send out volunteers and staff members — made up of attorneys, legal observers, educators, organizers and others — to verify and document ICE operations.

“ICE has not waited a single moment to begin separating hundreds of families and causing fear and concern in various communities throughout the U.S.,” CHIRLA organizing director Pedro Trujillo said in a statement. “LARRN’s message to the community is that they are not alone and together we will stand strong against the Trump administration’s cruel and unjust policies targeting working immigrant families in the U.S.”

Los Angeles, and California as a whole, has a large immigrant population.

In December, the L.A. City Council adopted an ordinance to make L.A. a “sanctuary city” and declared that city resources and personnel would not be used to help immigration officials in enforcing federal immigration laws.

And on Monday, Orange County Sheriff Don Barnes said his department will continue to focus on state and local laws while leaving immigration enforcement to federal officials, though the sheriff did express frustration that California’s sanctuary law limits local law enforcement’s ability to help federal immigration agents.

Members of the Ventura County Law Enforcement Coordinating Committee, which includes the Ventura County district attorney, its sheriff’s department and others, also said they did not intend to help federal immigration agents.

“To be very clear, Ventura County law enforcement has not historically participated in the enforcement of immigration laws,” said a statement from the committee. “We do not intend to change that practice.”

California state law already limits how much local enforcement can work with federal immigration authorities on certain enforcement efforts. That law was upheld by the U.S. Supreme Court after it was challenged during Trump’s first term.

Still, Trump continues to signal his desire to punish cities and states that refuse to cooperate with ICE. He’s tasked federal officials with reviewing whether so-called “sanctuary jurisdictions” could lose federal funding.

Since Thursday, ICE has arrested more than 3,550 people nationwide, according to daily numbers provided by the agency. Operations have been carried out in such cities as Newark, N.J., Chicago and Honolulu.

Since resuming office last week, Trump has moved swiftly to fulfill a campaign promise to crack down on illegal immigration.

On his first day back in office, the president signed executive orders to beef up security along the U.S southern border.

And Tom Homan, Trump’s “border czar,” said in a recent interview with ABC News that while immigrants who are considered a threat to public safety or national security would be targeted first for deportation, ultimately, “if you’re in the country illegally, you’re on the table.”

“You’ve got to remember: every time you enter this country illegally, you’ve (committed) a crime. … So if you’re in the country illegally, you’ve got a problem,” he said.

To further the president’s plans for mass deportation, the Trump administration announced Friday it was expanding a fast-track deportation authority to allow immigration officers to deport migrants without first appearing before a judge.
