The Republican-controlled Congress is set to send a bill approving the Keystone XL oil pipeline to President Barack Obama, who has vowed to veto it.

The House is expected to pass the bill easily Wednesday, capping weeks of debate over one of Republicans' top priorities — a bill authorizing the construction of the much-delayed pipeline. Yet support in both the Senate and House has not been enough to override a veto, and backers of the bill said they are already strategizing ways to get it approved by other means, such as attaching it to a broader energy or spending bill.

The pipeline has exposed larger divisions between environmentalists concerned about global warming and potential oil spills against supporters who argue that the $8 billion project will create jobs and boost U.S. energy security. One of the measures added to the bill by the Senate states that climate change is not a hoax, which could make some conservative Republicans think twice. (AP)
