The Democratic-controlled House of Representatives is poised to give final approval on Tuesday to a Senate-passed bill temporarily increasing the government's borrowing ceiling to $28.9 trillion, deferring the risk of default until early December.

Democrats, who control the House by a razor-thin majority, were anticipated to maintain party discipline and approve the contentious $480 billion debt ceiling hike, only to face another deadline in the coming weeks to prevent a historic debt default and a brief government shutdown.

Last week's vote to raise the debt ceiling - usually a routine step - devolved into a partisan brawl, with Republicans attempting to link the measure to President Joe Biden's goal of passing a multibillion-dollar package of bills that would fund infrastructure and social services while combating climate change.

About the U.S. House of Representatives

With the aid of 11 Republicans, the Democratic-controlled Senate enacted a bill last Thursday extending the $28.4 trillion statutory ceiling as the country approached an expected Oct. 18 deadline when the Treasury Department will no longer be able to make debt payments to lenders.

Republicans in the House have stated that they will vote against it. Mitch McConnell, the Senate Republican leader, was one of 11 Republicans who voted for the interim debt ceiling hike and has pledged not to vote for another extension in December. He intends to compel Democrats to adopt a special "reconciliation" mechanism that would allow the next debt ceiling hike to be passed solely by Democratic voters.
