Eleven U.S. Democratic senators on Thursday urged President Barack Obama to make a final decision on whether to approve TransCanada's Keystone XL crude oil pipeline from Canada to the U.S. Gulf Coast no later than May 31.
"We need a definitive timeline laid out, a timeline that reduces the comment period for federal agencies, officials and other entities," the senators wrote to Obama. "We cannot miss another construction season."
The group included several lawmakers expected to face tough re-election battles this year, notably Mary Landrieu of Louisiana, who chairs the Senate Energy Committee.
Also signing on were Heidi Heitkamp of North Dakota, Mark Begich of Alaska, Joe Donnelly of Indiana, Kay Hagan of North Carolina, Joe Manchin of West Virginia, Claire McCaskill of Missouri, Mark Pryor of Arkansas, Jon Tester and John Walsh, both of Montana, and Mark Warner of West Virginia.
