A Congressional bill to approve a controversial oil pipeline project has been rejected by the White House.

FOX News Radio's Jon Decker reports:

Just hours after receiving the GOP-backed legislation approving the Keystone XL pipeline, the President responded with a swift veto.

Republicans and some Democratic supporters of the pipeline are warning that the President's rejection of the bill won't be the last word in the long-running fight over the Keystone project.

Republicans are already weighing their next moves, and at the top of that list is a likely attempt to override the veto.
