HONOLULU (REUTERS) - Fresh from the long legislative fight to prevent a "fiscal cliff" of tax hikes and spending cuts, President Barack Obama warned today that the United States could not afford further budget showdowns this year or in the future.

Mr Obama, who returned to Hawaii for a family vacation shortly after the House of Representatives passed a compromise bill on Tuesday, said in his weekly radio and Internet address that the new law was just one step toward fixing the country's fiscal and economic problems.

"We still need to do more to put Americans back to work while also putting this country on a path to pay down its debt, and our economy can't afford more protracted showdowns or manufactured crises along the way," he said in the address, broadcast today.

"Because even as our businesses created 2 million new jobs last year - including 168,000 new jobs last month - the messy brinkmanship in Congress made business owners more uncertain and consumers less confident." Government data released on Friday showed the US unemployment rate remained at 7.8 per cent in December.

Lawmakers in the Senate and the House passed legislation this week that raised tax rates for the wealthiest Americans while making Bush-era tax cuts for the middle class permanent.

It was a victory for Mr Obama, who campaigned for re-election largely on a promise to achieve that goal.

Republicans have indicated that they are ready for another fight over the US debt ceiling. Representative Dave Camp, delivering his party's weekly address, warned, at least indirectly, that they would expect spending cuts in return for raising the ceiling again.

"Many of our Democrat colleagues just don't seem to get it. Throughout the fiscal cliff discussions, the president and the Democrats who control Washington repeatedly refused to take any meaningful steps to make Washington live within its means," Mr Camp said.
