White House, GOP Discuss Potential Debt Limit Pact

White House officials and congressional Republicans are reaching toward a potential end to their bitter debt limit showdown, raising hopes that a deal could be in place by Tuesday to avert a possible federal default.

A top White House official says "we don't have a deal" between President Barack Obama and Republicans in Congress to avoid a crippling default.

But senior White House adviser David Plouffe tells NBC's "Meet the Press" that both sides are generally in agreement on an emerging package that would cut the deficit in two stages, with key details still being worked out.

After weeks of strident partisan conflict, the two sides were discussing an accord that would raise the government's borrowing authority in two steps by about $2.4 trillion and cut federal spending by slightly more, according to knowledgeable officials.

Congress would also have to vote on a constitutional amendment requiring a balanced federal budget, a top-flight GOP goal. Unlike a bill approved Friday by the Republican-run House, none of the debt limit increase would be tied to congressional approval of that amendment.

Details of a possible accord began emerging Saturday night after Senate Majority Leader Harry Reid, R-Nev., said on the Senate floor that the two sides were trying to nail down loose ends and complete an agreement.

"I'm glad to see this move toward cooperation and compromise, and hope it bears fruit," he said.

A Democratic official said that while bargainers were not on the cusp of a deal, one could gel quickly. A Republican said there was consensus on general concepts but cautioned there were no guarantees of a final handshake. Both spoke on condition of anonymity to reveal details of confidential talks.

Any pact would have to quickly pass both chambers of Congress after a rancorous period that has seen the two parties repeatedly belittle each other's efforts to end the standoff.

Even so, the deal under discussion offers wins for both sides. Republicans and their tea party supporters would get spending cuts at least as large as the amount the debt ceiling would grow and avoid any tax increases. For President Barack Obama and Democrats, there would be no renewed battle over extending the borrowing limit until after next year's elections.

Under the possible compromise, the debt limit would rise by an initial $1 trillion.

A second, $1.4 trillion increase would be tied to a specially created congressional committee that would have to suggest deficit cuts of a slightly larger amount. If that panel did not act - or if Congress rejected their recommendations - automatic spending cuts would be triggered that could affect Medicare and defense spending, two of the most politically sacrosanct programs.

Obama and Democrats have been insisting on a one-shot debt ceiling increase of around $2.4 trillion, enough to last until 2013. Bowing to GOP pressure, they eventually agreed to include an equal amount of spending cuts and dropped their earlier bid for tax increases.

In a bill the House approved Friday - and the Senate rejected - Republicans would initially extend federal borrowing authority by $900 billion, accompanied by $917 billion in spending cuts. They would tie a second $1.6 trillion debt limit boost to spending cuts of up to $1.8 trillion and approval of the balanced budget amendment.

The government has exhausted its $14.3 trillion borrowing limit and has paid its bills since May with money freed up by accounting maneuvers.

The Treasury Department has said it will run out of available cash on Tuesday. The administration has warned that an economy-shaking default would follow that could balloon interest rates and wound the world economy.
