A nationwide crackdown to apprehend thousands of illegal immigrants across the country began late Saturday in the nation's largest city and several other places, according to an official.
Immigration and Customs Enforcement (ICE) was expected to resume its previously announced plan to apprehend thousands of illegal immigrants who've been given orders to leave the country, targeting people in at least 10 cities. The sweeps were expected to start Sunday, but New York City Mayor Bill de Blasio said Saturday on Twitter that ICE agents had already taken action in New York.
The ICE raids began late Saturday and into the early morning hours on Sunday in "a number of jurisdictions," not just New York City, a senior administration official confirmed to Fox News.
De Blasio said the raids in New York City took place in parts of Brooklyn and Manhattan.
"Receiving reports of attempted but reportedly unsuccessful ICE enforcement actions in Sunset Park and Harlem," the mayor said. "@NYCImmigrants and advocates are connecting with residents and distributing resources door to door."
Advocates are coaching them on their rights, including instructions not to respond if agents knock on the door unless shown a warrant signed by a judge. The Democratic mayor has said his city would not cooperate with ICE.
Mark Morgan, acting commissioner of Customs and Border Protection, told "FOX & friends" on Sunday that the raids were about "enforcing and maintaining the integrity of the system."
"This is about the rule of law," Morgan said. "Those individuals who remain here illegally, especially those who've received due process more than any other nation in the world would provide someone that came here illegally, to including those with final orders, that there are consequences to those that remain here illegally. That's what today is about. "
Morgan, the former head of ICE, differed to disclose details about the raids. But he blasted mayors of cities who pushed back against the crackdown, calling their actions “unconscionable.”
"This is about going after individuals here illegally," he said. "Any city, any law enforcement agency that resists, does not cooperate, they're actually putting those cities in higher danger."
On Friday, ICE Acting Director Matthew Albence said targets were on an "accelerated docket" of immigration court cases for predominantly Central Americans who recently arrived at the U.S. border in unprecedented numbers. Similar operations occurred in 2016 under President Obama and in 2017 under President Trump.
The operation will target people with final deportation orders on 10 major court dockets, including Chicago, Los Angeles, New York, and Miami. Albence said that doesn't mean arrests will be limited to certain areas. Authorities will go where their investigations lead, even if it's five states away from where the case is filed.
Trump said authorities were "focused on criminals as much as we can before we do anything else."
"It starts on Sunday and they're going to take people out and they're going to bring them back to their countries or they're going to take criminals out, put them in prison, or put them in prison in the countries they came from," the president said.
Administration officials have said they are targeting about 2,000 people, which would yield about 200 arrests based on previous crackdowns.
Trump has said on Twitter that his agents plan to arrest millions of immigrants in the country illegally.
