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.
