Obama vetoes Keystone pipeline approval bill

President Barack Obama on Tuesday swiftly delivered on his vow to veto a Republican bill approving the Keystone XL oil pipeline from Canada, leaving the long-debated project in limbo for another indefinite period. The Senate received Obama's veto message and Senate Majority Leader Mitch McConnell immediately countered by announcing the Republican-led chamber would attempt to overturn the veto by March 3. Obama rejected the bill hours after it was sent to the White House.
