House Speaker Kevin McCarthy’s last-ditch plan to keep the federal government temporarily open collapsed in dramatic fashion Friday as a robust faction of hard-right holdouts rejected the package, making a shutdown almost certain.

McCarthy’s right-flank Republicans refused to support the bill despite its steep spending cuts of nearly 30% to many agencies and severe border security provisions, calling it insufficient.

The White House and Democrats rejected the Republican approach as too extreme. The vote was 198-232, with 21 hard-right Republicans voting to sink the package. The Democrats voted against it.
