A group of House Republican rebels voted down Speaker Kevin McCarthy’s short-term spending bill Friday, raising the odds that the federal government will shutdown in less than 48 hours.

The bill was rejected 198-232, with 21 conservative holdouts led by Representative Matt Gaetz breaking from their party to vote against it. McCarthy spearheaded the measure, which would have temporarily funded the government for 30 days through October 31, as a way to stave off a shutdown while Republicans worked to pass other appropriations bills.

“We actually need a stop-gap measure to allow the House to continue to finish its work, to make sure our military gets paid, to make sure our border agents get paid as we finish the job that we’re supposed to do,” McCarthy told reporters.

If Congress does not enact and President Biden does not sign a funding bill, the government is set to close at 12:01 a.m. on Sunday.
