The Republican leader in the US House of Representatives Eric Cantor has said he does not support the bill passed by the Senate to avert steep tax rises and spending cuts.
He said he was concerned about a "lack of spending cuts in the bill" and that Republicans in the House are searching for a way forward.
Mr Cantor expressed his unhappiness with the measure to reporters as he left a closed-door meeting with fellow House Republicans.
America's financial crisis has been averted, not solved. We've had the fiscal cliff. Now get ready for the debt abyss.
Democrats and Republicans have so far failed to agree on an alternative plan to the tax increases and spending cuts scheduled for January 1.
