Two Chicago aldermen have proposed eliminating sanctuary-city protections for foreign nationals convicted of or arrested for certain crimes.

Aldermen Raymond Lopez and Silvana Tabares say their proposed amendment to the Welcoming City Ordinance would allow the city to work with federal immigration officers. Lopez said the measure would only apply when an individual has been arrested for or convicted of gang crimes, drug crimes, prostitution-related activities such as human trafficking, or sex crimes involving minors.

“The goal of this amendment to our Welcoming City Ordinance is to keep people safe: to keep our citizens safe and to keep the undocumented, who are just following the law and awaiting their time until they can legalize their status, safe by removing those individuals who are here choosing, with emphasis on ‘choosing,’ to engage in certain, specific, illegal activities here in the city of Chicago,” Lopez told The Center Square.

Alderwoman Julia Ramirez said she is strongly opposed to the amendment, citing the potential for the Chicago Police Department to collaborate with federal immigration officials.
