The Politico reported that Jill Hazelbaker, campaign communications director for Republican presidential nominee John McCain would "be there to vote on the bill."
Hazelbacker said the Arizona senator "expects to be able to support this bill, but we need to see what
emerges from the Senate," she told Fox News.
As for Democratic presidential nominee Barack Obama, he, too, will return to Washington for the vote.
Obama spokeswoman Jen Psaki told the Washington publication the campaign was monitoring the vote schedule.
"Senator Obama has always said that when the vote is close and his vote is needed, he will be there," Psaki said.
The Senate would vote on the package Wednesday.
Both candidates indicated Sunday they likely would support the bill.
