Democrats have largely thrown their support behind a bipartisan proposal worth $908 billion while there is optimism Republicans will also come on board soon.
Republican Senator Bill Cassidy, who helped put the plan together, said he was confident Donald Trump and Senate Majority Leader Mitch McConnell will come "on board".
"President Trump has indicated that he would sign a $908 billion package -- there's only one $908 billion package out there and it's ours," he told Fox News on Sunday.
"The pain of the American people is driving this and I'm optimistic that both of those leaders will come on board," he added.
And Democratic senator Dick Durbin said: "This is our last chance before Christmas and the end of the year to bring relief to families across America in the midst of a public health crisis.
We've got a few remaining issues. I think we can work them out."
In morning trade, Asia markets were mixed, with Hong Kong, Tokyo, Shanghai and Seoul all down but Sydney, Jakarta and Wellington up. Singapore and Taipei were flat.

Johnson has threatened he will walk away from the talks if Britain does not get what it wants.
"Talks are in the same position now as they were on Friday.
We have made no tangible progress. It's clear this must now continue politically," a senior UK government source said.
"Whilst we do not consider this process to be closed, things are looking very tricky and there's every chance we are not going to get there."
The pound has swung wildly this week and on Tuesday it was slightly lower.
Still, National Australia Bank's Rodrigo Catril said: "From an optimistic perspective, the good news is that nothing has broken yet and the hopes of an EU-UK trade deal remain alive.
