The White House today threatened to veto the latest House Republican transportation bill over its inclusion of a provision fast-tracking the Canada-to-U.S. Keystone XL oil pipeline. The veto recommendation from the Office of Management and Budget effectively recommits President Obama to opposing the $7 billion project -- despite his support for its southern leg connecting Oklahoma oil terminals with the Gulf Coast -- on the same day that Nebraska's governor signed a state law intended to speed up the controversial selection of a new Cornhusker route for the pipeline.
