Funding deadlock over immigration policy reforms has paused the DHS funding, forcing a partial shutdown.

A partial U.S. federal government shutdown officially began early Saturday after lawmakers missed the funding deadline, but major leaders in Washington say they expect it to be much shorter than last year’s 43-day closure and could end as soon as Monday or Tuesday once the House acts.

Senate Democrats blocked two Republican-backed measures Thursday to keep the department open, including a short-term funding extension for two weeks as negotiations continue.

Democrats have insisted that the federal government place meaningful new limits on immigration officers — including an end to wearing masks — before they vote to fund D.H.S. They point to polls that show broad disapproval of ICE’s tactics, and some of their voters are demanding that they not back down.

Although Fetterman called for the immigration operation in Minneapolis to “immediately end,” he vowed to never vote to shut down the government.
