WASHINGTON: The Department of Homeland Security entered a partial shutdown Saturday as US lawmakers fight over funding the agency overseeing much of President Donald Trump’s immigration crackdown.

Thousands of government workers, from airport security agents to disaster relief officials, will either be furloughed or forced to work without pay until funding is agreed upon by Congress.

At the center of the budget dispute is the department’s Immigration and Customs Enforcement (ICE), whose agents killed two US citizens amid sweeping raids and mass protests in Minneapolis.

Democrats oppose any new funding for DHS until major changes are implemented over how ICE conducts its operations.

In particular, they have demanded curtailed patrols, a ban on ICE agents wearing face masks during operations and the requirement that they obtain a judicial warrant to enter private property.
