US House Republicans unveiled a spending bill Saturday that would keep federal agencies funded through 30 September, pushing ahead with a go-it-alone strategy that seems certain to spark a major confrontation with Democrats over the contours of government spending.

The 99-page bill would provide a slight boost to defense programs while trimming non-defense programs below 2024 budget year levels. That approach is likely to be a non-starter for most Democrats who have long insisted that defense and non-defense spending move in the same direction.
