WASHINGTON (Reuters) – President Donald Trump’s incoming administration is reviewing plans to visit Chicago next week after it became clear, Trump’s “border kingpin” Tom Homan told the Washington Post in an interview on Saturday.

The new administration “has not made a decision,” said Homan, the former director of US Immigration and Customs Enforcement, according to the report. “We are looking into this leak and will take a decision based on this leak,” he added.

ICE did not immediately respond to a request for comment.

Officials and activists said the Trump administration would begin a sweep of several US cities shortly after taking office on Monday, with Chicago seen as the first stop.

Dulce Ortiz, president of the Illinois Coalition for Immigrant and Refugee Rights, told Reuters that about 200 ICE agents are expected to launch raids in the Chicago area on Monday at 5 a.m., with the aim of arresting people who are going to work or starting their day.

The enforcement is expected to continue for several days, he said. An ICE spokeswoman referred questions to Trump’s transition team, which did not immediately respond to a request for comment.

Reuters reported on Friday that agents would also carry out attacks in New York and Miami. The Wall Street Journal reported Friday that ICE will operate for a week in Chicago with hundreds of agents.

Trump said in an interview with NBC News on Saturday that starting the mass deportations he promised during his election campaign would be a priority. But he declined to name the target cities or when the deportations would begin.

“It’s going to start very quickly,” Trump said. “We have to get rid of terrorists in our country.”

Homan himself appeared to confirm the raids that took place on Saturday, telling Fox News that “enforcement operations” will quickly pursue some of the alleged 700,000 immigrants who are in the US illegally and under deportation orders. He has indicated that the efforts will take place in several cities.

“President Trump has been clear from day one … he’s going to protect the border and he’s going to do the deportment,” Homan told Fox News before Trump’s inauguration on Monday.

Homan said the organization had planned the project well and identified the people who needed to be followed.

“Anything that wants to do this is well planned, and the whole team will be there for the safety of the police,” he said.

Asked how the closures would be received in so-called sanctuary cities, which have pledged not to use city resources to engage in organized crime, Homan said sanctuary city policies are “regrettable.”

Regarding the people who are suspected to be already in the local prisons, he said that the situation in these cities is a threat to the safety of the people. The cities “will free up public safety threats in the area … and enforce (ICE) enforcement in the communities,” Homan said.

He urged the city officials to help the people who have been expelled from the country, but added: “We will do this with or without their help.
