Senate Democratic leader Chuck Schumer has warned that Democrats will oppose a measure to fund the Department of Homeland Security, raising the risk of a partial government shutdown. The move comes as lawmakers face a deadline to pass funding legislation before current appropriations expire.

Schumer's opposition could complicate efforts to keep the agency operational, as DHS relies on annual appropriations to maintain its operations. A shutdown would affect thousands of federal employees and disrupt various security and immigration functions. The standoff reflects ongoing partisan divisions over government spending priorities and border security policies.

The threat of a shutdown adds uncertainty to federal operations and could impact businesses that work with DHS contractors and grant recipients. While essential personnel would remain on duty, non-essential services could be suspended, potentially delaying projects and disrupting supply chains that depend on federal approvals.
