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.

Lawmakers in both parties say the shutdown is likely to end early next week.

House Minority Leader Hakeem Jeffries told Speaker Mike Johnson on Saturday that Democrats won’t help Republicans pass a funding bill to reopen the government if they attempt to fast-track the measure Monday,

The Senate passed a measure to avert a shutdown on Friday. But with the House on recess, funding for broad stretches of the federal government has technically lapsed.

The US Senate passed a compromise spending package on Friday, clearing a path for Congress to avert a costly government shutdown amid a battle in Washington over changes to the Trump administration’s immigration enforcement tactics.

The Senate passed a deal between Democrats and the White House to fund the government, but the House won’t vote until Monday. The shutdown will have little impact if it is brief.
