WASHINGTON (AP) - Democratic presidential candidate Bernie Sanders says President Barack Obama should reject the Keystone XL oil pipeline before heading to Paris next month to finalize a global climate agreement.

WASHINGTON (AP) Democratic presidential candidate Bernie Sanders says President Barack Obama should reject the Keystone XL oil pipeline before heading to Paris next month to finalize a global climate agreement.

Sanders said rejecting the pipeline now would show "bold leadership" in the fight to slow climate change, which Sanders called "a major, major, major planetary crisis."

The pipeline's developer, Calgary-based TransCanada, has asked U.S. officials to delay consideration of the Alberta-to-Texas pipeline. The request potentially puts off a decision until the next U.S. president takes office in 2017.

Sanders said Obama should ignore the company's request and act decisively to reject the controversial pipeline. He said such an action would signal to the rest of the world that the United States will "walk the walk" on climate change.
