WASHINGTON (CNN)– House Democratic aides denied Wednesday that work is already underway on another stimulus package. The push back came a day after Speaker Nancy Pelosi suggested more stimulus spending might be needed and the top Democrat on the Appropriations Committee said he had already instructed his staff to begin working on a bill.

But multiple Democratic aides told CNN another stimulus plan is not in the works, and they maintained that Democratic leaders believe it will take more time to know whether the first recovery package is effective before taking up another bill.

One leadership aide said that House Appropriations Chairman David Obey got ahead of himself when he told CNN Tuesday evening that his committee was considering another stimulus package, though he had cautioned there was no timeline for moving it.

This aide said House Democratic leaders are letting the current stimulus play out, and that it will be "at least several months, as we get toward the end of the year and see where we are" before they would consider another stimulus bill.

Another Democratic aide said that the Appropriations committee "is not putting pen to paper. We think it's too soon to do [a second stimulus] now."

Brendan Daly, spokesman for Speaker Nancy Pelosi said in a statement, “As the Speaker indicated, Congress will continue to closely monitor economic conditions to determine if further action is needed to stimulate the economy.”

Asked if there is a contingency plan or discussions going on behind the scenes about what a second stimulus would include, one leadership aide insisted there are none, saying the contingency plan is to let the Obama Administration’s housing and financial stabilization programs run their course.

But even as Democrats tried to tamp down talk about the need for more taxpayer money to help spur an economic recovery, Republicans criticized Democrats for excessive spending.

Tennessee Republican Senator Lamar Alexander, reacting to reports of a second stimulus bill, told reporters Wednesday, "We don't even know what was in the first stimulus bill package yet."

Referring to the budget recently outlined by President Obama and the stimulus package just enacted, Alexander said, " I believe this is more spending, more taxes, and more debt than most American families expected or than most American families can afford."

House Republican Conference Chairman Mike Pence, R-Ind., piled on: "I think the fact that Democrats are already talking about stimulus 2 suggests that Democratic leadership has apparently concluded that their stimulus bill has already failed. That's fairly remarkable after just a couple of weeks." Pence said if there is a second stimulus, Republicans would fight for more tax relief for small business and families instead of more government spending.
