The Senate narrowly rejected a GOP-sponsored measure that would have bypassed the Obama administration's objections to the Keystone XL pipeline and allowed construction on the controversial project to begin.
Fifty-six senators voted in favor of the amendment -- four short of the 60 required for approval.
The proposed 1,700-mile long pipeline expansion, intended to carry crude oil from Canada's oil sands to the U.S. Gulf Coast, has become a political lightning rod. Supporters, including the oil industry, say it's a vital job creator that will lessen the country's dependence on oil imported from volatile regions.
Opponents say the pipeline may leak, and that it will lock the United States into a particularly dirty form of crude that might ultimately end up being exported anyway.
President Barack Obama rejected a bid in January to expedite the pipeline, arguing that a decision deadline imposed by Congress did not le ave sufficient time to conduct necessary reviews. Administration officials have said the president may still eventually give the project a green light, though critics accuse him of trying to delay a final decision until after the November election.
Obama personally lobbied wavering Democrats to block passage of the amendment.
