The US Department of Homeland Security (DHS) is set to face a partial shutdown as Congress did not approve funding before the deadline. The funding expires at midnight in Washington, DC, on Saturday (05:00 GMT). The Senate adjourned without passing a DHS budget. The House started its weeklong recess earlier. The shutdown results from a standoff triggered by immigration controversies in Minnesota, where immigration raids resulted in the deaths of two US citizens in January. Democrats have demanded changes to Immigration and Customs Enforcement (ICE) operations. Their list includes banning ICE agents from wearing masks, stopping racial profiling, and ending raids at sensitive places like schools and churches. Democrats said they will block DHS funding without these reforms. Republicans, controlling both Senate and House, called these demands unreasonable. The Senate’s filibuster rule requires 60 votes for such bills, but only 52 voted for funding, 47 opposed. Senate Democrat Chuck Schumer said, "The Republican bill on the floor allows ICE to smash in doors without warrants, to wear masks and not be identified, to use children as bait for their parents." He added, "No funding for ICE until it is reined in, until the violence ends." Many lawmakers had already left Washington before the vote, with some attending international conferences. A prolonged shutdown may force many federal workers to work without pay and disrupt services. Travel groups warn this could cause flight delays due to TSA staff shortages. However, DHS immigration operations will largely continue because ICE and Customs and Border Protection have separate funding from last year's budget act. This shutdown follows a recent announcement ending the Trump administration's immigration operation in Minnesota. The dispute highlights growing Democratic anger over ICE's harsh tactics and Trump’s deportation efforts. A recent poll showed 65% of Americans believe ICE has gone too far in its crackdown. The funding deadlock is key as midterm elections approach.
