Negotiations in the Senate to reopen the Department of Homeland Security broke down again Wednesday, with Democrats and Republicans rejecting each other’s latest proposals and leaving the shutdown unresolved.

At the center of the impasse are Democratic demands for new limits on the operations of Immigration and Customs Enforcement, particularly in light of President Donald Trump’s expanded deportation efforts.

Democrats turned down a Republican proposal that would have funded most of DHS while excluding immigration enforcement, arguing that any agreement must include substantive reforms to ICE practices.

Republicans, in turn, rejected a Democratic counterproposal that would have imposed new restrictions on immigration agents. The exchange left both sides effectively at the same stalemate that began more than a month ago when the department shut down.

Senate Minority Leader Chuck Schumer said Democrats were seeking to reopen DHS while placing “common-sense guardrails” on enforcement activities. According to people familiar with the proposal, those measures included barring agents from wearing masks and requiring judicial warrants before entering private homes—conditions the Trump administration has previously opposed.

Senate Majority Leader John Thune dismissed the proposal as unworkable, saying Democrats were revisiting demands that had already been rejected.

The Republican plan put forward earlier in the week would fund most DHS operations while excluding ICE units responsible for detentions and deportations. GOP lawmakers suggested addressing immigration enforcement separately in a future bill, potentially alongside election-related provisions sought by Trump.

However, Democrats argue that separating funding from oversight would allow enforcement practices to continue without accountability, further entrenching the deadlock.

With both sides holding firm, negotiations appear to be at an impasse, prolonging the DHS shutdown and its impact on federal operations.
