WASHINGTON -- House Speaker John Boehner says Republicans will advance legislation to temporarily extend the government's ability to borrow to meet its obligations.
Boehner said the measure would advance if President Barack Obama agrees to negotiate over reopening the government and to "start to deal with America's pressing problems."
Obama has said consistently that Republicans must reopen the government and prevent the threat of a first-ever government default before he'll negotiate over the budget and other conditions Republicans have sought.
Boehner also said he would appoint House negotiators to try to sort out differences between vastly different House- and Senate-passed budget blueprints. Boehner said: "It's time for leadership. It's time for these negotiations and this conversation to begin."
Treasury Secretary Jacob Lew warned Congress Thursday of "irrevocable damage" that an unprecedented federal default could cause.
Lew testified to the Senate Finance Committee on the 10th day of a partial federal shutdown and one week before Lew has said the government will deplete its ability to borrow money. Most economists say the default that could result would deal a staggering blow to the world economy. Some Republicans have downplayed the harm a default would cause.
Lew warned that failure to renew the government's ability to borrow money "could be deeply damaging to the financial markets, the ongoing economic recovery and the jobs and savings of millions of Americans." It would also leave the government unsure of when it could make payments ranging from food aid to Medicare reimbursements to doctors, he said.
"The United States should not be put in a position of making such perilous choices for our economy and our citizens," the secretary said. "There is no way of knowing the irrevocable damage such an approach would have on our economy and financial markets."
As Lew spoke, Obama prepared to host top House Republicans at the White House in hopes of finding an opening in an impasse that has shuttered much of the government and threatens federal default.
The game of Washington chicken over increasing the debt limit - required so Treasury can borrow more money to pay the government's bills in full and on time - already has sent the stock market south, spiked the interest rate for one-month Treasury bills and prompted Fidelity Investments, the nation's largest manager of money market mutual funds, to sell federal debt that comes due around the time the nation could hit its borrowing limit.
Wednesday featured lots of activity but no progress toward ending the budget and debt limit impasses.
Obama had House Democrats over to the White House, while Republican conservatives heard a pitch from the House Budget Committee chairman, Rep. Paul Ryan, R-Wis., on his plan to extend the U.S. borrowing cap for four to six weeks while jump-starting talks on a broader budget deal that could replace cuts to defense and domestic agency budgets with cuts to benefit programs like Medicare and reforms to the loophole-cluttered tax code. Curbs to "Obamacare" were not mentioned.
At the White House, Obama told House Democratic loyalists that he still would prefer a long-term increase in the nation's $16.7 trillion borrowing cap but said he's willing to sign a short-term increase to "give Boehner some time to deal with the tea party wing of his party," said Rep. Peter Welch, D-Vt.
A midday meeting Wednesday between the two top House Republicans and Democrats, meanwhile, yielded no progress. Rival aides to Boehner and Democratic leader Nancy Pelosi of California even disagreed over who asked for the meeting. Aides said Pelosi had a long-ignored request for a meeting with Boehner that Boehner unexpectedly granted on short notice.
Obama invited the entire House GOP to the White House on Thursday but Boehner opted to send a smaller squadron of about 20 mostly senior members, which prompted White House Press Secretary Jay Carney to issue an unusual statement criticizing the move to exclude tea party Republicans from the session.
"The president thought it was important to talk directly with the members who forced this economic crisis on the country about how the shutdown and a failure to pay the country's bills could devastate the economy," Carney said.
The frustrating standoff in Washington is weighing on each side's poll numbers, but Republicans are taking the worst drubbing. A Gallup poll put the approval rating for the Republican Party at a record-low 28 percent. Polls have consistently said the Republicans deserve the greater share of blame for the shutdown.
Also Wednesday, the House voted 252-172 to reopen the Federal Aviation Administration. Democrats generally opposed the measure and the White House issued a veto threat, saying the government should be reopened all at once, not piecemeal.
There was a brief moment of unity when the House voted 425-0 to let the Pentagon pay death benefits to the families of fallen U.S. troops.
Republicans said Congress had passed and Obama had signed legislation last week to permit the payments, but the Defense Department said otherwise. As Republican leaders were pushing toward a vote on the bill making it explicit, Defense Secretary Chuck Hagel announced a charity would pick up the death benefit costs instead.
