U.S. House Speaker Kevin McCarthy said on Thursday that Republicans could act on their own to address the federal government’s debt ceiling, after months of demands that President Joe Biden first agree to spending cuts went nowhere. In the latest sign of growing Republican exasperation over Biden’s refusal to negotiate a deal on spending in exchange for a debt ceiling hike, McCarthy said his party is close to agreeing on a package that could pass the House of Representatives without participation from the president or Democrats in Congress.
