(AP) — Democrats are threatening to block funding for the Homeland Security Department when it expires in two weeks unless there are “dramatic changes” and “real accountability” for U.S. Immigration and Customs Enforcement and other law enforcement agencies who are carrying out President Donald Trump’s campaign of federal immigration enforcement in Minnesota and across the country.

It’s unclear if the president or enough congressional Republicans will agree to any of the Democrats’ larger demands that the officers unmask and identify themselves, obtain judicial warrants in certain cases and work with local authorities, among other asks. Republicans have already pushed back.

House GOP lawmakers are demanding that some of their own priorities be added to the Homeland Security spending bill, including legislation that would require proof of citizenship before Americans register to vote and restrictions on sanctuary cities. There’s no clear definition of sanctuary jurisdictions, but the term is generally applied to state and local governments that limit cooperation with federal immigration authorities.
