Republican infighting in the US House of Representatives is stalling spending bills and threatening a government shutdown at the end of September. The House voted against advancing a $886 billion defense appropriations bill for fiscal year 2024 due to 5 Republican conservatives joining Democrats in opposition. Disagreements within House Speaker Kevin McCarthy's Republican majority also block a short-term funding measure to keep government agencies operating past September 30th. Hardliners want assurances that total fiscal year 2024 discretionary spending will not exceed $1.47 trillion agreed to previously.
