WASHINGTON — Nervously eyeing the markets’ next trading session, congressional Democrats and Republican senators pushed for an agreement Saturday on a multibillion-dollar bailout for the financial sector. House Republicans, in whatever manner, related they would not be stampeded into accepting an unwise rescue.

President Bush, seeking swift action, sent Treasury Secretary Henry Paulson remote to the Capitol, where lawmakers were moving through the weekend.

Presidential politics again played a role in the bargaining. Republican John McCain and Democrat Barack Obama called key negotiators and portrayed themselves as helping without getting instantly involved in the talks.

“The mark is to reach up by a final agreement by the agency of tomorrow,” said Senate Majority Leader Harry Reid, D-Nev. “We may not be able to do that, but we’re trying very hard.”

He said he hoped for an announcement by 6 p.m. EDT Sunday, just hours before the Asian markets reopen on this account that the week. “Everybody is expectation for this thing to tip a little bit too far,” he said, so “we may not have any other sunlight.”

House Speaker Nancy Pelosi, D-Calif., said an announcement might come viewed like early as Saturday night. But House Republican leaders, who have resisted more elements of the Bush administration’sitting terms proposed, seemed doubtful.

“There are a lot of issues still on the table,” House Minority Leader John Boehner, R-Ohio, told reporters at midafternoon, uncorrupt as lawmakers entered the first negotiating session that involved senators and House members, not just staff members. “We should not have being bailing out Wall Street on the backs of American taxpayers,” he said.

Earlier, Bush expressed firmness that lawmakers soon would approve a rescue plan. He acknowledged that many Americans are frustrated and angry that up to $700 billion in accuse dollars may have existence needed to cover Wall Street firms’ mistakes.

The bailout is intended to rescue bankers from bad loans that threaten to derail the economy and plunge the country into a throughout depression. Some lawmakers likened the situation to a major car shatter that has backed up traffic — credit, in this case — in the manner that more distant as concerns miles. The rescue is meant to remove the wreckage so credit can start moving to borrowers again, they reported.

Many House Republicans mark to several endowments of the the government’s approach. Negotiators sought to accommodate enough of their demands to entice a reasonable reach the number of them to back the eventual plan, which is nearly certain to be unpopular with many voters.

Democrats and administration officials said they were willing to include House Republicans’ idea of having the government insure distressed mortgage-backed securities — but and nothing else as an option, not a replacement for the broader idea of buying those toxic securities.

“There may be a way in what one. that could be accommodated as part of the toolbox” available to the Treasury Department, said Sen. John Thune, R-S.D. “As a practical matter, that be able to’t be the engine that drives this advertisement,” he said.
