WASHINGTON (AP) — The Bush administration tossed out no lifeline for the teetering auto industry Sunday and a Republican who blocked $14 billion in loans said it appeared the White House hadn’t decided what to do.

With President George W. Bush on an unannounced trip to Iraq, White House officials said they did not expected to make an announcement either Sunday or Monday.

The administration is considering ways to provide emergency aid to General Motors Corp. and Chrysler LLC, which have said they could run out of cash within weeks without federal aid.

Sen. Bob Corker, R-Tenn., said he spoke with the White House early Sunday. “I don’t think they yet know what they’re going to do,” he said. Ron Gettelfinger, the president of the United Auto Workers, said the union had not held discussions with the White House.

The aid is expected to benefit General Motors and Chrysler and discussions involve the amount of funding and any potential conditions. Ford Motor Co. has said it has enough cash to survive 2009 but asked Congress for a line of credit in case the financial markets deteriorate.

“I’m optimistic they’re going to do something significant. I don’t think the White House wants bankruptcy at one of the Big Three automakers as part their legacy,” said Sen. Sherrod Brown, D-Ohio.

Last week, Congress failed to approve $14 billion in loans to help the automakers. The plan would have provided short-term financing to the industry and create a “car czar” who would ensure that the money would transform the Detroit automakers into competitive companies.

The administration, following the legislative defeat, said they were considering several options, including using money from the $700 billion financial bailout fund to provide loans to the carmakers.

Corker and other Republicans sought a compromise that would have insisted the carmakers to restructure their debt and bring wages and benefits in line with those paid by Toyota, Honda and Nissan in the United States. The legislation died when Republicans demanded upfront pay and benefit concessions from the United Auto Workers that union leaders rejected.

Corker urged the White House to seek similar concessions from the auto companies and their unions in return for the money. “Of course, the benefit they have — they don’t have to negotiate. They can say this money is available but it’s only available under these conditions,” he said in a broadcast interview.

Sen. Debbie Stabenow, D-Mich., countered that Republican leaders in the Senate did not want an agreement and the loans were needed to buy time for the companies to restructure.

“Manufacturing is on the edge in this country. This is not the time for a political agenda,” Stabenow said.

The UAW’s Gettelfinger said the failure of the legislation showed that Congress should stay “away from the bargaining table.”

The administration has several options. It could tap the $700 billion financial rescue bailout fund to provide loans to the carmakers or use part of that fund as a kind of collateral for emergency loans the automakers could get from the Federal Reserve.

The administration also could do nothing, leaving open the possibility that one or more of the automakers could go bankrupt. But the White House has warned a collapse of the auto industry would severely hurt the economy.

The White House is keeping President-elect Barack Obama and his advisers informed of the discussions. If administration officials choose not to provide the money now, the Obama team could wait for the new Congress, which will have stronger Democratic majorities.

Providing aid to the companies could represent a change for the White House, which has previously insisted that the Wall Street rescue plan should be used solely to help financial institutions.

Gov. Jennifer Granholm, D-Mich., said other countries were providing aid to their automakers and the loans were essential to help make the U.S. less dependent on foreign oil.

If the companies don’t get help, “we’ll be replacing our reliance on foreign oil with a reliance on foreign batteries because it’s going to be the battery that’s driving the electric vehicle in the future,” Granholm said.

Corker was on CBS’ “Face the Nation,” as was Brown, and “Fox News Sunday,” where he appeared with Stabenow. Gettelfinger was on “Late Edition” on CNN. Granholm was on “Meet the Press” on NBC.
