The House will vote on Friday to defy President Obama's veto threat and approve the Keystone XL pipeline. It will be the 10th time in four years the House has moved to approve or accelerate a decision on the controversial oil-sands project since Republicans took control of the lower chamber in 2011. Here is a rundown of those votes.
1. July 26, 2011. The House voted 279 to 147 to pass the North American-Made Energy Security Act, a bill that would have required Obama to approve or reject the pipeline by Nov. 1, 2011. The bill did not get a vote in the Senate.
2. Dec. 13, 2011. The House voted 234 to 193 to pass the Middle Class Tax Relief and Job Creation Act, a bill with a provision that would have required Obama to approve or reject the pipeline within 60 days. The Keystone provision was stripped out in the Senate before the final version was signed into law.
3. Dec. 23, 2011. The House unanimously approved the Temporary Payroll Tax Cut Continuation Act, a bill that was signed into law by Obama. The legislation included a provision requiring presidential approval of Keystone XL within 60 days unless the administration deemed the project not in the national interest. The legislation was unanimously approved by the Senate and signed into law by the president. Obama subsequently rejected the permit for Keystone XL, citing the "rushed and arbitrary deadline" set by the law and requesting that TransCanada, the company seeking to build Keystone XL, reapply for a permit.
