"I'm convinced that by Sunday we will have an agreement that people can understand on this bill," predicted Massachusetts Rep. Barney Frank, a key Democrat in eight days of up-and-down talks designed to stave off an economic disaster.
House Speaker Nancy Pelosi added that "progress is being made," although the day came and went without senior lawmakers from both parties sitting down together.
Neither she nor Frank divulged details at a late-afternoon news conference in the Capitol, though there was word of one fresh Democratic concession.
Pelosi told fellow Democrats during a closed-door meeting that the idea of letting judges rewrite mortgages to help bankrupt homeowners avoid foreclosure won't be a part of the emergency legislation. That provision, pushed by several Democrats, would be a deal-breaker for Republicans whose votes are needed to pass the measure, she said, according to lawmakers at the meeting.
Democrats and Bush administration officials also said they were willing to include House Republicans' idea of having the government insure distressed mortgages - but only as an option, rather than a replacement for the administration's more sweeping approach.
All sides continue to warn of severe economic aftershocks if Congress fails to pass a bailout bill, but the deal hinges on whether the President Bush can turn back a revolt by members of his own party, reports CBS News correspondent Bob Orr.
Democratic and Republican staff aides met into the night on Capitol Hill. They were going line by line through legislative proposals in an attempt to clear the way for lawmakers to bargain over the weekend even as presidential contenders John McCain and Barack Obama agreed during their presidential debate Friday night that Congress must act soon.
Asked directly whether he intends to vote for a rescue plan taking shape in Congress, McCain said, "I hope so. ... sure."
"We haven't seen the language yet," Obama said. "I do think there is constructive work being done."
Meanwhile, new details emerged of a remarkably tumultuous White House meeting on Thursday. With the session breaking up in disarray, according to two participants, President Bush issued an appeal, saying, "Can't we just all go out and say things are OK?" The group around the table, congressional leaders as well as McCain and Obama, spurned the presidential request for a publicly united front.
Earlier in the White House meeting, Democrats peppered House Republican leader John Boehner of Ohio with questions about the details of an alternative he was backing. "I don't know what the hell they are," Bush said at one point," recalled one person who was in the room. All the participants spoke on condition of anonymity, saying the meeting was private.
Bush sought to coax the talks back to life on Friday, prodding lawmakers in a morning appearance to "rise to the occasion" - and quickly.
In a sign of progress, House Republicans dispatched their second-ranking leader, Rep. Roy Blunt of Missouri, to join the talks after their objections to an emerging compromise had brought negotiations to a standstill the day before. They demanded "serious consideration" for their plan.
"We want to see a deal happen - there's no doubt about it," said Rep. Eric Cantor, R-Va.
The legislation the administration is promoting would allow the government to buy bad mortgages and other sour assets held by investors, most of them financial companies. That should make those companies more inclined to lend and lift a major weight off the national economy that is already sputtering.
But a significant number of lawmakers, including many House conservatives, say they're against such heavy federal intervention. Under the GOP plan, the government would insure the distressed securities rather than buy them. Tax breaks would provide additional incentives to invest.
"I think what we're expecting in these negotiations is looking for ways to really protect taxpayers and to make sure that Wall Street pays its fair share of this problem," House Minority Leader John Boehner told CBS Evening News anchor Katie Couric. "I just don't think it's fair to take $700 billion of taxpayer funds, put them on the line without Wall Street also stepping up to me solve this problem."
Key Democrats were just as adamant about not giving the president too much latitude in negotiations.
"I can only tell you what we're being told by others, that if we don't step up, these problems we're seeing in our economy could go far worse," Sen. Chris Dodd, chairman of the Senate Banking Committee told Couric. "I'm not going to give this president as blank check for $700 billion without some conditionality on it. I won't do that and I don't think my colleagues will either."
The crisis was hardly limited to the U.S.
Bush held a lengthy Oval Office meeting with British Prime Minister Gordon Brown that focused on how the problems were spreading, then said, "I told him the plan is big enough to make a difference, and I believe it will be passed."
Presidential politics weighed heavily and unpredictably on the election-season effort to stave off a full-blown economic crisis.
After announcing earlier in the week he would suspend his campaign and return to the capital until there was an agreement, Republican McCain abruptly with Democratic rival Obama.
