WASHINGTON (AP) — Democratic leaders say a proposal from the White House is “incomplete and insufficient” as they are demanding new restrictions on President Donald Trump’s immigration crackdown and threatening a shutdown of the Homeland Security Department.

Senate Democratic leader Chuck Schumer and House Democratic leader Hakeem Jeffries said in a statement late Monday that a White House counterproposal to the list of demands they transmitted over the weekend “included neither details nor legislative text” and does not address “the concerns Americans have about ICE’s lawless conduct.” The White House proposal was not released publicly.

The Democrats’ statement comes as time is running short, with another partial government shutdown threatening to begin Saturday. Among the Democrats’ demands are a requirement for judicial warrants, better identification of DHS officers, new use-of-force standards and a stop to racial profiling. They say such changes are necessary after two protesters were fatally shot by federal agents in Minneapolis last month.
