WASHINGTON (AP) — The Republican-controlled Senate has failed to override President Barack Obama's veto of a bill approving the Keystone XL oil pipeline.

The 62-37 vote Wednesday was the latest chapter in the fight between the GOP-led Congress and the White House over energy policy. It was the first of many possible veto showdowns to come in Obama's final term.

Proponents of the bill have said since its introduction that they didn't have the vote of two-thirds of the Senate needed to override Obama's veto.

The $8-billion pipeline would transport oil harvested from Canada's tar sands to pipelines linked to Gulf Coast refineries. Obama said that the bill circumvented the well-established process for approving cross-border pipelines, which must be determined to be in the national interest.
