President Barack Obama on Friday rejected the proposed Keystone XL pipeline, ending the political fight over the Canada-to-Texas project that has gone on for much of his presidency.<br />Secretary of State John Kerry concluded the controversial project is not in the country's national security interest, and Obama announced from the White House that he agreed with the decision.<br />"America is now a global leader when it comes to taking serious action to fight climate change, and frankly approving this project would have undercut that leadership," Obama said.<br />The move comes as the White House continues to promote its environmental agenda and efforts to fight climate change.
