Mayor Rahm Emanuel declared today that Chicago will remain a "sanctuary city" as he sought to reassure undocumented immigrants who are fearful of deportation in Donald Trump's presidency.

Other cities, like Seattle, San Francisco, Los Angeles, Minneapolis, New York and Philadelphia, have also re-affirmed their sanctuary policies following Tuesday's election.

Emanuel, former chief of staff to President Obama, said Chicago "always will be a sanctuary city."

"To all those who are very nervous after Tuesday's election, you are safe in Chicago, you are secure in Chicago and you are supported in Chicago," he said.

Trump said on "60 Minutes" last night that he's focused on border security - including building the wall - and on deporting or incarcerating an estimated 2 to 3 million criminal illegal aliens in the country.

He said after those actions are taken, a discussion will take place about how to handle other undocumented immigrants

"We're going to make a determination on the people that they're talking about who are terrific people, they're terrific people but we are gonna make a determination at that," he said.

The Outnumbered hosts discussed Emanuel's announcement today, with Pete Hegseth saying he "welcomes this showdown" and Trump should stand up for what he campaigned on.

"This is why people voted for Donald Trump. Because they see lawlessness in their country. ... You either have a country or you do not. If you're here illegally that's one thing but especially if you're a criminal and you've broken our laws. Why should you get sanctuary anywhere?" he asked.

Meghan McCain questioned what Emanuel would say if a Chicago resident was to be killed by an illegal immigrant in the city. She said this is the issue that Trump ran on and won.

Rachel Campos-Duffy said undocumented immigrants who are otherwise law-abiding probably want criminal illegal aliens to be dealt with so that their neighborhoods are as safe as possible.
