ROUGH CUT (NO REPORTER NARRATION)<br/> <br />The U.S. Senate on Tuesday narrowly failed to pass a bill that would have approved construction of the controversial Keystone XL pipeline, rejecting a measure the House of Representatives approved last week.<br/> <br />The vote count was 59-41 in favor, but 60 "ayes" would have been needed to assure passage. Fourteen Democrats voted for the bill, joining all 45 Republicans who voted to support the pipeline.<br/> <br />TransCanada Corp's $8 billion pipeline would help transport crude oil from Canada to the Gulf of Mexico, but is opposed by environmentalists.<br/> <br />Had the bill passed, it would likely have been vetoed by President Barack Obama.
