'You are safe, you are secured'

Chicago on Monday joined several major US cities in affirming that it will remain a "sanctuary city" for immigrants, in defiance of President-elect Donald Trump.

Los Angeles, New York, Seattle and San Francisco have made similar affirmations since Trump's election on Tuesday, vowing to refuse to jail undocumented immigrants in jail for deportation purposes and pledging that public services will continue to be offered regardless of legal status.

"To all the children and all the families who are unsure of their place because of what happened Tuesday," Chicago Mayor Rahm Emanuel said at a press conference.

"You are safe, you are secure and you are supported in the city of Chicago."

Emanuel, a Democrat who was chief of staff during President Barack Obama's first term, said young undocumented people in particular will still be able to go to school and qualify for free community college education.

"That speaks volumes to where our values are," he said.

Trump, a Republican, campaigned on a promise to deport millions of undocumented immigrants. In an interview that aired on the CBS "60 Minutes" news program over the weekend, Trump said he plans to immediately deport or jail as many as three million immigrants with criminal records, upon taking office.

Experts estimate there are as many as 11 million foreigners living illegally in the United States, many of them Central and Southern Americans long-established in the country.

Since 2009, the Obama administration has deported 2.4 million immigrants from the country. But Obama has also offered a reprieve to young people who were brought to the US by their parents -- so-called "Dreamers." By executive order, he granted them temporary residency rights, allowing them to go to school and work.
