Hundreds of people are expected to be targeted in the operation, the person said. As with previous immigration operations, so-called incidental arrests are possible, meaning people who aren’t targeted but lack legal status could also be detained if encountered during the sweep, the person said.

The person spoke on the condition of anonymity to discuss internal deliberations that have not been publicly disclosed. The operation was first reported by The New York Times.

Homeland Security spokesperson Tricia McLaughlin said the agency would not discuss “future or potential operations.”

“Every day, ICE enforces the laws of the nation across the country. What makes someone a target of ICE is not their race or ethnicity, but the fact that they are in the country illegally,” McLaughlin said.

Trump and other officials in his administration have used increasingly harsh language in recent days against Somalis living in the U.S., after a conservative news outlet, City Journal, claimed that taxpayer dollars from defrauded government programs have flowed to the Somali group al-Shabab.

Last month, Trump said he was terminating Temporary Protected Status for Somali migrants living in Minnesota, a legal safeguard against deportation for immigrants from certain countries. A report produced for Congress in August put the number of Somalis covered by the program at just 705 nationwide.

Responding to news reports about the potential enforcement activities, Minnesota Gov. Tim Walz said in a post on X, “We welcome support in investigating and prosecuting crime. But pulling a PR stunt and indiscriminately targeting immigrants is not a real solution to a problem.”

Trump has claimed immigrants from Somalia were “completely taking over the once great State of Minnesota” and has demeaned Walz, the Democratic vice presidential nominee last year.

Treasury Secretary Scott Bessent said in a social media post Monday that his agency was “investigating allegations that under the feckless mismanagement of the Biden Administration and Governor Tim Walz, hardworking Minnesotans’ tax dollars may have been diverted to the terrorist organization Al-Shabaab.”

Jaylani Hussein, a Somali American who is executive director of the Minnesota chapter of the Council on American-Islamic Relations, said his group has heard of “less than a dozen” immigration arrests within the local Somali community in recent days.

But Hussein said around 95% of Somalis in Minnesota are U.S. citizens, so the numbers of those at earlier stages of the immigration process are a “pretty small” proportion of the community. He said they estimate that 50% of the community was born in the U.S.

“We believe this is political rhetoric and an attack against our community,” Hussein said. “But additional ICE agents means additional pressure on the wider immigrant community,” he said, referring to Hispanics and other Africans.

Hussein said the reported crackdown plan is yet another example of the Trump administration “demonizing the Muslim community.” And he said it’s not new that when somebody in the community commits a crime, the entire community will get accused. He said that’s been true of other ethnic groups through American history.
