Sanctuary Cities

Chicago's Mayor Rahm Emanuel is pushing back against the federal government.

On Monday, the city is filing suit against the Department of Justice, which announced it would withhold millions of dollars in police grant money from so-called sanctuary cities.

Emanuel is suing because he says new rules for a federal crime-fighting grant go against the Constitution and the city's values.

"Chicago will not let our police officers become political pawns in a debate," Emanuel said.

Attorney General Jeff Sessions is narrowing the scope of an executive order on so-called sanctuary cities.

A federal judge in California last month blocked a key part of that order, reasoning that the Trump administration had overstepped by threatening to yank federal money from those places.

A federal judge ruled Tuesday that the Trump administration cannot withhold federal funds from jurisdictions that limit their cooperation with immigration authorities, commonly known as sanctuary cities.

The Justice Department is following through on an executive order to withhold as much as $4.1 billion in federal grants from so-called "sanctuary cities," generally defined as places where local law enforcement limit their cooperation with federal authorities on immigration enforcement.
