A bill to ban the Environmental Protection Agency from controlling greenhouse gases has died in the U.S. Senate.
Democrats defeated the bill on Wednesday by a vote of 50-50. The measure was part of a Republican effort to repeal findings that say greenhouse gases cause climate change and endanger human health.
It would have prevented the EPA from regulating gases blamed for global warming.
On Thursday, the House is expected to pass an identical bill. It has little chance of becoming law since the White House has threatened to veto any bill that reaches the president's desk.
In a statement Wednesday night, White House press secretary Jay Carney said the administration was "encouraged" by the Senate's actions to defend the EPA "by rejecting efforts to roll back EPA's common-sense steps to safeguard Americans from harmful pollution."
Critics of the administration's action on global warming looked at the vote's outcome differently, noting that a majority of senators in some way voted to restrict the EPA's regulation of heat-trapping gases.
"When all is said and done, a bipartisan majority in the Senate issued a sobering message to EPA. suggesting it's time to reverse course and put Congress back in charge of America's energy policy," Sen. Jim Inhofe, R-Okla., said in a statement.
