President Donald Trump confirmed Friday that Immigration and Customs Enforcement agents would conduct weekend raids this Sunday to deport immigrants with outstanding orders to leave the country.
Trump said the raids will target criminals, but immigration advocates say the agency is increasingly targeting families who have recently entered the country. The president did not not give a specific time for when the ICE operations would take place on Sunday.
"There's nothing to be secret about. Can I tell you what? There's nothing to be secret about. ICE is law enforcement, they're great patriots. They have a tough job. Nothing to be secret about," Trump told reporters at the White House on Friday.
"If the word gets out, it gets out. Hundreds of people know about it. It's a major operation. So if the word gets out, it gets out. 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. We're focused on criminals as much as we can before we do anything else," Trump said.
A law enforcement official briefed on the operation told ABC News agents would target only undocumented immigrants with final removal orders, who would be arrested and in most cases deported.
The same official said the operation will not arrest so-called "collaterals," those people who happen to be with the targeted individual. The official described this operation as a consolidated effort of something ICE does all the time.
ICE has declined to comment on the timing of any raids.
Major cities across the U.S. on Thursday were bracing for sweeping deportation raids this weekend, the second time in less than a month that Trump administration insiders have signaled roundups were imminent.
Trump also brushed off criticism from mayors who are against the action, saying the criticism is only from sanctuary cities.
"The mayors in sanctuary cities, a mayor like de Blasio who's probably the worst mayor in the country. I don't know what his attitude is, nobody does, because he doesn't work very hard. Nobody knows what he does. But a guy like de Blasio probably wouldn't want the raid. Many mayors do. Most do. You know why? They don't want to have crime in their cities or states," he said.
When raids were reportedly planned last month, mayors of cities like Los Angeles, Baltimore, and Chicago pushed back, saying the city and local law enforcement would not cooperate with ICE. Mayor Lori Lightfoot in Chicago specifically directed the Chicago Police Department not to help ICE or allow them to access the department's databases.
Mayor LaToya Cantrell and DHS confirmed there will be no immigration enforcement this weekend in New Orleans, where the city is bracing for dangerous flooding from tropical storm Barry.
The raids were intended as a massive show of force against undocumented immigrants by President Donald Trump, who last month tipped his hand when he vowed on Twitter that "millions" would be deported.
While administration officials have called that estimate an exaggeration, they confirmed there are 2,000 people in as many as 10 cities who have been identified as a top priority for deportation -- many of them families.
Those raids were called off last month after Trump gave Democrats two weeks to change the nation's laws that guarantee the right for people to apply for asylum.
House Speaker Nancy Pelosi on Thursday said "there may be some possibilities for what we can do" but that it would take some time. She called targeting non-criminal families "heartless" and said it was up to Trump's supporters to press him to abandon his plan.
"I'm going to appeal to people of faith, the faith-based organizations to appeal to the president. ... They put him in office and they have a better voice for this," she told reporters.
The large-scale operation would be a departure from past practices, in which U.S. Immigration and Customs Enforcement has focused its resources on rounding up people with criminal records who "pose a threat to public safety." This approach would include families and send ICE officers to people's homes.
"As always, ICE prioritizes the arrest and removal of unlawfully present aliens who pose a threat to national security, public safety and border security," according to a statement.
The effort to deport individuals over failing to appear in immigration court is now being challenged by the American Civil Liberties Union. A lawsuit filed on Thursday by the ACLU argues that the government has continuously failed to properly inform individuals of their court dates -- an attempt to preempt the massive ICE raids that are reportedly expected to begin this weekend.
The lawsuit, according to a statement from the New York Civil Liberties Union, "describes in detail, these refugees failed to appear because of massive bureaucratic errors and, in some cases, deliberate misdirection by immigration enforcement agencies."
"The agencies' flagrant and widespread errors made it impossible for people to know when their hearings were being held," the statement continued.
"The Trump administration's threats against immigrants run roughshod over basic fairness and due process," said New York Civil Liberties Union Executive Director Donna Lieberman in a statement. "For the many families who came here as refugees fleeing violence, deportation is a death threat. We will fight to ensure no one faces this kind of peril without having their case considered in court."
One undocumented woman who has lived in the U.S. for 20 years told ABC News, "How do I protect myself? Mainly one just stays locked inside one's home and tries to not leave unless it's completely necessary -- like to work, to buy food and just stay locked inside."
"That's mainly how I spend my time," the woman, who spoke to ABC News on the condition of anonymity, said in Spanish. "You don't want to venture out to do activities, why? Out of fear that the police will get you, investigate you, question you, there's a lot of fear, a lot of anxiety, a lot of uncertainty that one carries inside due to being unstable."
John Cohen, a former senior official at the Homeland Security Department and ABC News contributor, said launching deportation raids at people's homes would consume the agency's resources.
"What people need to understand is that every ICE agent used in this operation will not be available to go after criminal aliens, gang members, terrorists" or other priorities, he said.
Jorge-Mario Cabrera, spokesman for the Coalition for Humane Immigrant Rights in Los Angeles, or CHIRLA, said the group is already aware of two families who encountered ICE agents in the last week, including one case in which a dozen agents arrived at a home. Cabrera said no one was detained in those incidents because they knew they did not have to open the door.
He said CHIRLA attorneys, who are prepared to post bail and offer representation for immigrants who are taken into custody, are activating a rapid response network and will be on watch for increased ICE activity over the weekend.
Immigration advocates in Chicago were doing the same.
"We're here today because the Trump administration is threatening our communities again," said Mony Ruiz-Velasco, president of the board for the Illinois Coalition for Immigrant and Refugee Rights. "We are also here today because we will not allow that to happen and we are ready, we are ready to defend each other and defend our communities and we are organized."
Senate Democrats on Thursday proposed legislation that they said would provide alternatives to migrant detention at the border.
"Donald Trump and some of his right wing allies in media would have you believe these are all hardened criminals. They're not. They're simply seeking a better life for themselves and their children," said Senate Democratic Leader Chuck Schumer, D-N.Y.
"We're trying to send a message to the family units that 'don't come here and don't put your life at risk, your children's life at risk,'" he told ABC News last month.
