Chicago Mayor Rahm Emanuel has declared the city a Trump-free zone following President Donald Trump's decision to end the Deferred Action for Childhood Arrivals program.
DACA enables close to 800,000 undocumented immigrants who arrived in the U.S. as children to stay in the country legally, The Washington Post reports.
Congress now has six months to come up with a replacement.
Emanuel spoke to children during their first day back at school.
"To all the Dreamers that are here in this room, and in the city of Chicago, you are welcomed in the city of Chicago," Emanuel said, according to the Washington Examiner. "This is your home and you have nothing to worry about."
He said the city would resist Trump.
"Chicago, our schools, our neighborhoods, our city, as it relates to what President Trump said, will be a Trump-free zone," added Emanuel. "You have nothing to worry about."
However, Jeff Sessions, Trump's attorney general, argued that the announcement was about ensuring the rule of law.
"Such an open-ended circumvention of immigration laws was an unconstitutional exercise of authority by the Executive Branch," Sessions said of the DACA program.
The decision was a fulfillment of a campaign promise by Trump, who said in 2016 he would end DACA "immediately" if he was elected, NBC News notes.
After becoming president, Trump stated he would treat DACA recipients "with heart."
Hundreds of immigrants and their supporters protested the decision outside of the White House before Trump's Sept. 5 announcement. They carried signs that read "We are America," and "We want education, down with deportation," The Washington Post reports.
“This president lied to the community," Gustavo Torres, executive director of the immigration advocacy group CASA, told the Post, according to Salon. "For many months, he said, ‘I love the Dreamers.’ He lied to us, we cannot trust him. We are going to keep fighting, we are going to keep registering people to vote. We are going to win elections in Virginia this year. We are going to win the elections in 2018 and 2020.”
The crowd in front of the White House began chanting "shame on Trump" after the president made the announcement at around 11 a.m. on Sept. 5.
Police arrested a dozen protesters in New York near Trump Tower after they sat down in the road and blocked traffic.
"Trump is trying to scare us into hiding, to get us to back down," DACA recipient Erika Andiola, who was among those arrested, told the Post. "We're not going to back down."
The Federation for American Immigration Reform welcomed DACA's demise.
"DACA was an unconstitutional abuse of executive authority by President Obama..." Dan Stein, the group's executive director, said in a Sept. 5 statement. "...President Obama stated when he implemented DACA, there were no guarantees that the program would continue after he left office."
