Republicans are "rooting against" the U.S. and the world by way of their votes against climate change legislation, the economic stimulus, and healthcare reform bills, Rep. Henry Waxman (D-Calif.) asserted Monday.

"They want to play politics and see if they can keep any achievements from being accomplished, for fear they might become beneficial to the Democrats," said Waxman, one of the principal authors of the climate change legislation passed by the House on Friday, on MSNBC.

"So they're rooting against the country," Waxman added. "And I think in this case they're even rooting against the world, because the world needs to get its act together to stop global warming. I wish they were playing a more constructive role."

Waxman said that his climate change legislation would have to "defy conventional wisdom" in the Senate, where many observers have said it would have trouble attracting enough Republicans and centrist Democrats to survive a filibuster.

"I think we have to defy conventional wisdom and move this important legislation forward," the chairman of the Energy and Commerce Committee said. "It's going to help us become more energy independent, and that's important for our national security."
