passed by Congress as "a major milestone" and promised to sign the bill into law shortly.
With the enormous package aimed at reviving a foundering US economy, creating millions of new jobs and stemming home foreclosures which helped spark the global financial meltdown last year, Obama claimed the biggest political victory yet of his nascent administration.
"This is a major milestone on our road to recovery, and I want to thank the members of Congress who came together in common purpose to make it happen," Obama said in his weekly radio address.
The Congress late Friday approved the package of House of Representatives by a 246-183 margin.and fresh spending to salvage the broken US economy, with the Senate voting 60-38 to pass the measure after it cleared the
The passage sets the stage for Obama to sign it into law by his self-imposed February 16 deadline, timing that his spokesman Robert Gibbs said was possible provided the paperwork was completed quickly.
Obama expressed confidence that the plan "will save or create more than 3.5 million jobs over the next two years, ignite spending by business and consumers alike, and lay a new foundation for our lasting economic growth and prosperity."
The legislation, a product of hard-fought negotiations this week, allocates 120 billion dollars to infrastructure spending, including money for highways.
It also features nearly 20 billion dollars for renewable energy and 11 billion to modernize the US electrical grid -- steps former vice president Al Gore warmly endorsed weeks ago as a major downpayment on Obama's strategy for fighting climate change.
The bill includes tax cuts -- expected to benefit 95 percent of US families -- and tens of billions of dollars for, bolstering healthcare for the least well-off and funds to help cash-strapped states avoid cuts in services like education.
A provision inserted by Senate Democrats would also prohibit cash bonuses for top executives at large companies that receive money under the government's bailout program, US newspapers reported Saturday.
But Obama's victory was bittersweet, as lawmakers approved a compromise stimulus that was smaller than the president had requested, and most Republicans rebuffed his appeals to join Democrats in backing it.
"This isn't Monopoly money. It's real. It adds up, and it has to be paid back, by our children and by their children," said Republican Senate Minority Leader Mitch McConnell.
Senator Lisa Murkowski of Alaska, delivering the Republican party's response to the president Saturday, said "Republicans have been supportive of a stimulus plan all along" but were skeptical about whether one of the largest US government outlays in history would create jobs.
"Over the past few weeks, a serious difference of opinion has emerged over what an economic recovery plan should include," Murkowski said.
"Democrats, it seems, settled on a random dollar amount in the neighborhood of a trillion dollars and then set out to fill the bucket."
In his address, the president vowed to spend taxpayer dollars "with unprecedented accountability, responsibility, and transparency."
He said once the plan is put into action, a new website -- recovery.gov -- will allow Americans to watch where the money goes and weigh in with comments and questions.
But he cautioned that thewould be the beginning rather than the end of efforts to turn the economy around because "the problems that led us into this crisis are deep and widespread.
"For our plan to succeed, we must stabilize, repair, and reform our banking system, and get credit flowing again to families and businesses," said Obama.
"We must write and enforce new rules of the road, to stop unscrupulous speculators from undermining our economy ever again."
He also said the US government must stem the spread of foreclosures and do everything it can to help responsible homeowners stay in their homes.
Over the long term, the president said measures would be needed to tame the country's burgeoning federal deficit, but expressed confidence that Americans would be able to overcome the hardships.
"It will take time, and it will take effort, but working together, we will turn this crisis into opportunity and emerge from our painful present into a brighter future."
