President Obama's 70-minute White House meeting late Wednesday afternoon with congressional leaders, an effort to break the stalemate over the partial government shutdown, did nothing to help end the impasse.
"The President made clear to the Leaders that he is not going to negotiate over the need for Congress to act to reopen the government or to raise the debt limit to pay the bills Congress has already incurred," the White House said in a written statement after the meeting.
"The President remains hopeful that common sense will prevail, and that Congress will not only do its job to reopen the government, but also act to pay the bills it has racked up and spare the nation from a devastating default."
"We had a nice conversation, polite conversation," House Speaker John Boehner, R-Ohio, said following the meeting, but noted the president repeated that he will not negotiate on dialing back Obamacare.
He added that he hopes that Mr. Obama and Democrats will have a serious discussion about resolving their differences with House Republicans.
"All we're asking for is a discussion and fairness for the American people under Obamacare - which I would hope the president, and my Democratic colleagues in the Senate would listen to the American people and sit down and have a serious discussion about resolving these issues."
House Minority Leader Nancy Pelosi, D-Calif., said after the meeting, "We had some candid discussion."
But, Senate Majority Leader Harry Reid, D-Nev., added, "We are where we are. We're through playing these games" on Obamacare, he added.
Earlier Wednesday, Mr. Obama said that Wall Street should be worried about more serious consequences now that the government is closed for business and the debt limit deadline is just around the corner.
"This time's different," Mr. Obama said in an interview with CNBC that aired Wednesday afternoon. "I think they should be concerned."
U.S. markets were down when they closed on the second day of the government shutdown, but the political stalemate hasn't had significant consequences for Wall Street yet. The government closed down Tuesday because Republicans have insisted on delaying or dismantling the Affordable Care Act in the legislation Congress must pass to fund government operations; Democrats, however, refuse to use government funding as a bargaining chip. Meanwhile, if Congress doesn't raise the debt limit (the nation's legal borrowing authority) by Oct. 17, the U.S. risks defaulting on its loans.
Mr. Obama met at the White House with the CEOs of some of the nation's largest financial institutions earlier Wednesday, who warned that the government shutdown a failure to lift the government's debt ceiling could have an "extremely adverse" impact on an economic recovery.
The president told CNBC's John Harwood that he told the financial leaders "that it is not unusual for Democrats and Republicans to disagree -- that is the way our founders designed our government." However, he continued, "When you have a situation in which a faction [of Congress] is willing potentially to default on U.S. government obligations, then we are in trouble."
Democratic leaders in the Senate and Republican leaders in the House appeared to beWednesday. Mr. Obama said the current stalemate "is not a problem with Congress, per se -- this is a problem with a particular faction of the Republican Party."
People are tired of "this constant governing from crisis to crisis," he added. "Do we need to break that fever? Absolutely."
Once Congress re-opens the government and raises the debt limit, Mr. Obama said he'd be willing to work with lawmakers on longer-term economic reforms.
The president has at times lampooned Republicans for their insistence on dismantling Obamacare, and he acknowledged Wednesday, "Absolutely, I am exasperated."
Still, he said, "During the course of my presidency, I have bent over backwards to work with the Republican Party."
