Philadelphia won't allow U.S. Immigration and Customs Enforcement to use its arrest database after Aug. 31, the AP reports. Mayor Jim Kenney, a Democrat, accused ICE of wrongfully using the database to locate undocumented immigrants even without criminal records.

"We’re not going to provide them with information so they can go out and round people up.”

— Kenney

The big picture: This comes as some progressive Democrats, led by Alexandria Ocasio-Cortez, have latched on to an "abolish ICE" campaign. Republicans have just as quickly used the phrase as a political weapon against Democrats. Meanwhile, Trump's efforts to defund "sanctuary cities" such as Philadelphia are currently blocked by a federal judge's injunction.
