"I think there is a big premise that government spending and government expansion creates jobs, which is a flawed premise," Kingston told ABC News. "There was actually no debate on it. There is an assumption by Democrats that more government spending somehow is going to jump-start the economy."
Rep. Denny Rehberg, R-Mont., also a member of Appropriations, has concerns about how some of the funds would be overseen.
For instance, he supports weatherization of homes but is upset that House Democrats are proposing to increase government grants from $200 million to $6.2 billion. Rehberg said that it takes somebody 120 hours of instruction to gain certification to properly oversee the process. In Montana, he said, only four people have such certification.
"We don't have the trained people to go out and make sure it's done right," Rehberg said.
Others, however, believe that the stimulus plan doesn't go far enough.
Nobel Prize-winning economist and liberal New York Times columnist Paul Krugman said the plan isn't big enough.
President Obama met with members of both parties Friday, trying to push the bill through Congress.
"I recognize that there are still some differences around the table and between the administration and the members of Congress about particular details on the plan," the president said. "But what I think unifies this group is recognition that we are experiencing an unprecedented, perhaps, economic crisis that has to be dealt with and dealt with rapidly."
Obama and House Speaker Nancy Pelosi, D-Calif., said they expect the bill to clear Congress by President's Day, Feb. 16.
"Again, if not, there will be no recess, but I feel certain that we will succeed," Pelosi said.
Mark Zandi, chief economist and co-founder of Moody's Economy.com, warned that the government needs to avoid projects like the so-called Bridge to Nowhere, a proposed bridge to a small Alaskan island that eventually became a national symbol for government waste and pork-barrel spending.
"It's key that we don't build bridges to nowhere and don't do things that don't significantly help our economy either in the short or long run," Zandi said. "There is a line between projects that do the economy a service in the long run and projects that are driven for political purposes that aren't determined based on economic criteria; those are the projects we have to avoid."
Such "wacky proposals," he said, can harm the effectiveness of the stimulus package in more ways than one.
"The stimulus is more than dollars and sense, it's about shoring up confidence," Zandi said. "If taxpayers hear about money used for these kinds of things, it's going to undermine confidence, it's not going to shore it up."
An oversight board, he said, should be created to judge which proposals are "economically efficacious projects."
"Policymakers need to be very vigilant and put tight controls in place to ensure that stimulus money is used wisely," he added.
Tom Schatz, president of Citizens Against Government Waste, a Washington group that exposes what it calls pork-barrel spending, said the biggest question is: "What kind of jobs will be created and where will they be created and how does that stimulate the economy?
