The White House said on Thursday that President Barack Obama would consider any bill passed by Congress approving TransCanada's Keystone XL crude oil pipeline, but declined to say whether Obama would veto such a bill.

White House spokesman Josh Earnest said Obama is committed to his current review process for the pipeline, and said there was a clearly established precedent requiring a presidential decision on projects crossing international borders.
