“[T]he Keystone XL pipeline project … would connect Canadian oil sands to refineries in Texas.
The letter, signed by 53 senators, came a day after Nebraska’s governorapproved a revised route for the pipeline to travel through the state while avoiding ecologically sensitive areas.
The effort was lead by Senators John Hoeven, a Republican from North Dakota, and Max Baucus, a Montana Democrat, who announced the dispatch of the letter.
Nine Democrats also signed the latest letter, but this time were joined by 44 Republicans.
The State Department said on Tuesday that it has delayed a decision on whether to approve the pipeline beyond the first quarter of this year. Previously, State had said it would make a decision by that time.
