The US Vice President Joe Biden will meet with fellow Democrats in the House of Representatives today to discuss the "fiscal cliff" deal that he forged with Senate Republican Leader Mitch McConnell, a Democratic aide said.
Biden needed to help sell Senate Democrats on the deal before they joined Republicans at about 2am local time (7am GMT) in approving the measure.
US President Barack Obama has called for the House of Representatives to follow the Senate's lead and pass a 'fiscal cliff' deal to extend tax cuts for middle-class Americans and raise tax rates on top earners.
"While neither Democrats nor Republicans got everything they wanted, this agreement is the right thing to do for our country and the House should pass it without delay," Obama said in a statement after the Senate voted overwhelmingly to approve the legislation.
"There's more work to do to reduce our deficits, and I'm willing to do it. But tonight's agreement ensures that, going forward, we will continue to reduce the deficit through a combination of new spending cuts and new revenues from the wealthiest Americans," Obama said.
