President Barack Obama tugs on a tight pen cap after he signed an executive order establishing the Economic Recovery Advisory Board as its members look on, Friday in the East Room of the White House. Senate Democrats reached agreement with a small group of Republicans on Friday night on an economic stimulus measure at the heart of Obama’s plan for combatting the worst recession in decades.

Washington ? With job losses soaring nationwide, Senate Democrats reached agreement with a small group of Republicans on Friday night on an economic stimulus measure at the heart of President Barack Obama’s plan for combatting the worst recession in decades.

“The American people want us to work together. They don’t want to see us dividing along partisan lines on the most serious crisis confronting our country,” said Sen. Susan Collins of Maine, one of three Republican moderates who broke ranks and pledged their votes for the bill.

Democratic leaders expressed confidence that the concessions they had made to Republicans and moderate Democrats to trim the measure had cleared the way for its passage. No final vote was expected before today or Sunday.

Officials put the cost of the bill at $827 billion, including Obama’s signature tax cut of up to $1,000 for working couples, even if they earn too little to pay income taxes. Also included are breaks for homebuyers and people buying new cars. Much of the new spending would be for victims of the recession, in the form of unemployment compensation, health care and food stamps.

Republican critics complained that whatever the cost, billions were ticketed for programs that would not create jobs.

In a key reduction from the bill that reached the Senate floor earlier in the week, $40 billion would be cut from a “fiscal stabilization fund” for state governments’ education costs, though $14 billion to boost the maximum for college Pell Grants by $400 to $5,250 would be preserved, as would aid to local school districts for the No Child Left Behind law and special education.

A plan to help the unemployed purchase health insurance would be reduced to a 50 percent subsidy instead of two-thirds.

Tense negotiations

The agreement capped a tense day of backroom negotiations in which Senate Majority Leader Harry Reid, joined by White House chief of staff Rahm Emanuel, sought to attract the support of enough Republicans to give the measure the needed 60-vote majority. Democrats hold a 58-41 majority in the Senate, including two independents.

Uncertain of the outcome of the talks, Democrats called Sen. Edward M. Kennedy back to Washington in case his vote was needed. The Massachusetts senator, battling brain cancer, has been in Florida in recent days and has not been in the Capitol since suffering a seizure on Inauguration Day more than two weeks ago.

In addition to Collins, Republican Sens. Arlen Specter of Pennsylvania and Olympia Snowe of Maine pledged to vote for the legislation.

Important compromise

Whatever the price tag, the compromise marked a victory for the new president, who has veered between calls for bipartisanship and increasingly strong criticism of Republicans in recent days. And it indicated that Democratic leaders remain on track to deliver a bill to the White House by the end of next week.

Late Friday night, White House press secretary Robert Gibbs said, “On the day when we learned 3.6 million people have lost their jobs since this recession began, we are pleased the process is moving forward and we are closer to getting Americans a plan to create millions of jobs and get people back to work.”

Obama said earlier in the day that further delay would be “inexcusable and irresponsible” given Friday’s worst monthly unemployment report in a generation — 598,000 jobs lost in January and the national unemployment rate rising to 7.6 percent. And late Friday, federal regulators announced the closures of three banks, First Bank Financial Services in Georgia and Alliance Bank and County Bank in California, raising to nine the number of bank failures this year.

“The world is waiting to see what we’re going to do in the next 24 hours,” said Reid who has spent much of the week trying to balance demands among moderates in both parties against pressure for a larger bill from liberals in his own rank and file.
