Obama Tells G.O.P. Not to Tie Debt Ceiling to Fiscal Debate President Obama spoke to members of the Business Roundtable in Washington on Wednesday. WASHINGTON - President Obama warned Republicans on Wednesday not to use the debt ceiling as leverage on spending and tax decisions, saying he refused to engage again in the sort of brinkmanship that brought the country close to default last year and damaged its credit rating. In a speech to the Business Roundtable, Mr. Obama called that irresponsible. "That is a bad strategy for America, it's a bad strategy for your businesses and it is not a game that I will play," he said. Everybody here is concerned about uncertainty. There's no uncertainty like the prospect that the United States of America, the largest economy, that holds the world's reserve currency, potentially defaults on its debts. While saying he would not "play that game," a phrase he repeated, Mr. Obama did not say what he would do in response, but some Democrats have urged him in the past to simply raise the borrowing limit using his own executive authority and let the courts determine if he overstepped his constitutional bounds. He seemed to embrace a suggestion by John Engler, the Business Roundtable president, to raise the debt ceiling enough to last five years. "John is exactly right when he says that the only thing that the debt ceiling is good for as a weapon is just to destroy your credit rating," Mr. Obama said. Mr. Obama was reacting to reports that Republican leadership officials were looking for a fallback in the current debate to avert an end-of-the-year fiscal crisis. Some Republicans foresee accepting Mr. Obama's call to extend Bush-era tax cuts for the middle class while allowing them to expire for the wealthiest Americans, and then taking up the fight again when the nation's debt rises to the point that the statutory borrowing limit needs to be raised again, which could be in late January or February. Republicans view any vote to raise the debt ceiling as a chance to enforce more fiscal discipline on Mr. Obama. Speaker John A. Boehner has said any increase in borrowing capacity should be offset by spending cuts that exceed the increased debt. Mr. Obama has responded by proposing to take away the Congressional power to approve increases in the debt ceiling, but Mr. Boehner said last weekend that "Congress is never going to give up this power." Appearing before reporters on Wednesday, Mr. Boehner and other House Republican leaders implored Mr. Obama to sit down with them and begin negotiating in earnest to head off the looming fiscal crisis, but with flattery and aggravation, they made it clear that they were now playing on his turf. Mr. Boehner and his leadership team did not give an inch on their opposition to raising tax rates on the wealthy or their insistence that any deficit-reduction plan emphasize spending cuts. But the speaker sounded exasperated as he insisted that he had moved toward the president's position by agreeing to $800 billion in higher tax revenue over 10 years. The revenues we're putting on the table will come from guess who? The rich," he said, his voice rising. There are ways to limit deductions, close loopholes and have the same people pay more of their money to the federal government without raising tax rates. Representative Peter Roskam of Illinois, a member of the Republican leadership, appealed to Mr. Obama's own view of himself as a politician able to rise above partisanship, a characterization Republicans have rarely, if ever, agreed with. "I've seen an attribute in President Obama when we served together in the Illinois State Senate, where he was able to rise above donkeys and elephants and transform some very controversial issues in a way that was powerful," Mr. Roskam said, imploring the president to eschew the politics of the victor and seize "an unbelievable opportunity to be a transformational president, that is to bring the country together." The dueling public appearances underscored how far apart the two sides were, at least as a matter of principle. Mr. Obama's plan calls for $1.6 trillion in new taxes over 10 years, mainly through allowing rates to rise on income above $200,000 a year for individuals or $250,000 for families. He has also revived a year-old plan to trim health care and other mandatory spending by $600 billion over 10 years, but he also wants to spend $50 billion in the short term to help the economy.
