WASHINGTON (AP) -- President Barack Obama said Friday Congress has a "unique opportunity to do something big" and stabilize the U.S. economy for decades by cutting deficits at the same time it raises the national debt limit ahead of a critical Aug. 2 deadline. He said he was ready to make tough decisions -- such as on Medicare costs -- and challenged Republicans to do the same.
He attempted to turn the Republicans' opposition to any tax increases back against them, warning starkly that failure to raise the debt ceiling would mean "effectively a tax increase for everybody" if the government defaults, sending up interest rates.
Still, Obama said that "it's hard to do a big package" in deadlocked Washington, acknowledging Republicans are opposed to any new tax revenue as part of a deficit-cutting deal.
"If they show me a serious plan I'm ready to move," he said.
The president spoke at the White House Friday after five days straight of meetings with congressional leaders failed to yield compromise, and amid increasingly urgent warnings from credit agencies and the financial sector about the risks of failing to raise the government's borrowing limit.
Administration officials and private economists say that if the U.S. fails to raise its borrowing limit and begins to stop paying its bills as a result, the fragile U.S. economy could be cast into a crisis that would reverberate around the globe. Democratic and Republican congressional leaders agree on the need to avert that outcome, but that hasn't been enough to get Republicans to agree to the tax hikes on corporations and the wealthy sought by Obama -- or to convince Obama and Democrats to sign onto the steep entitlement cuts without new revenue that Republicans favor.
The president spoke at his third news conference in two weeks on an issue that is increasingly consuming Washington and his presidency.
The president said he was ready to make tough decisions such as restructuring Medicare so that very wealthy recipients would have to pay slightly more. He said he had stressed to Republicans that anything they looked at should not affect current beneficiaries, and he said providers such as drug companies could be targeted for cuts.
On Capitol Hill, meanwhile, Democrats and Republicans in the House emerged from closed-door meetings to reiterate their hardened stances. Republicans announced plans to call a vote next week on a balanced budget constitutional amendment that would force the government to balance its books.
Obama dismissed the idea, saying, "We don't need a constitutional amendment to do that. What we need to do is do our jobs."
Failure to reach compromise has focused attention on a fallback plan under discussion by Senate Republican leader Mitch McConnell and Senate Majority Leader Harry Reid. That plan would give Obama greater authority to raise the debt ceiling while setting procedures in motion that could lead to federal spending cuts.
Obama insisted the public was on his side in wanting a "balanced approach" that would mix spending cuts and the tax increases opposed by Republicans.
"The American people are sold," he said. "The problem is that members of Congress are dug in ideologically."
He renewed his pitch for a major package of some $4 trillion, about three-quarters of which would be spending cuts along with about $1 trillion in new revenue.
"We have a chance to stabilize America's finances for a decade or 15 years or 20 years if we're willing to seize the moment," the president said, adding later that everyone must be "willing to compromise."
"We don't need more studies, we don't need a balanced budget amendment," Obama said. He said lawmakers simply needed to be able to make tough decisions and stand up to their political bases.
