CHICAGO — A South Side alderman is slamming a flyer found in neighborhoods around the city asking black Chicagoans to report suspected undocumented residents to immigration agents.

The flyer says that "Sanctuary city Policies endanger the lively hood[sic] of every american [sic], while violating federal law and destroying the black community." The flyer claims there will be a reward of $3,000 to $10,000 "per illegal reported" and asks that people "help Atty. General Jeff Sessions Help US Black People."

“The flyer offers outrageous and baseless claims that Latino immigrants are taking jobs away from African-American Chicagoans," said 15th Ward Ald. Raymond Lopez. "Don’t fall for this phony argument."

He added: “This flyer is a fraud, and an effort by some nameless entity to divide us and get people to sell their own neighbors, like Judas Iscariot, for a few pieces of silver. We all know how history remembers Judas."

Lopez's office, which called the flyers "racist," has had reports of the flyers in Englewood and Roseland. The same flyer also was seen posted near a West Pullman construction site and on the West Side.

Earlier this week, the Trump administration scaled back a threat to withhold funding from sanctuary cities, including Chicago, as Attorney General Jeff Sessions vowed to yank only grants used to fight crime and terrorism — not all federal funds, as the president originally threatened.

After taking office, President Donald Trump signed an executive order against sanctuary cities that declared that "jurisdictions that willfully refuse to comply [with federal immigration laws] are not eligible to receive federal grants except as deemed necessary for law enforcement purposes."

In April, a judge blocked Trump's order, saying it contained "broad and threatening language" that "impermissibly" threatened cities like Chicago. determined to protect undocumented immigrants with the loss of all federal grants.

A phone number on the flyer seen Wednesday is the official tip line for the Department of Homeland Security.
