After weeks of debate and a roller-coaster amendment process, the US Senate advanced a bill Thursday authorising immediate construction of the controversial Keystone XL oil pipeline. The Canada-to-US pipeline has been a top priority for Republicans in the new Republican-controlled Congress, but it faces a veto threat from President Barack Obama. Senators voted 62 to 35 to end debate on the bill, which has taken most of January, and move to a vote on final passage, which is expected later Thursday.
The House has already passed its version of the bill. But because the Senate added some amendments, the House either needs to act on the Senate version or the two chambers must negotiate a final version and pass it. Overcoming a presidential veto requires a two-thirds majority, and it would be a heavy lift for supporters to obtain 67 votes in the 100-member Senate. Keystone XL, first proposed by TransCanada six years ago, would transport crude oil from the oil sands of Alberta, Canada to refineries along the US Gulf Coast. Republicans - and some Democrats - hail it as a 1,179-mile (1,900-kilometer) shovel-ready construction project that would create 40,000 jobs and boost US energy security.
