Sen. David Vitter (R-La.) has pointed the finger of blame at Senate Majority Leader Harry Reid (D-Nev.) for blocking a new amendment related to the Keystone XL Pipeline project.

"Every single Republican wants a vote on the Keystone XL pipeline, but Reid is singlehandedly, stubbornly blocking it from coming to a vote," Vitter said in a press release.

The Associated Press reports that Reid prevented a vote on a Republican amendment to the Keystone XL Pipeline proposal Wednesday, plus a measure that would have stopped the Environmental Protection Agency from imposing new greenhouse gas regulations on coal-burning power plants.

Around a dozen Democratic senators are behind the Keystone XL pipeline proposal, and all 45 Republican senators support it.

The news follows the Obama administration's announcement last month that it would indefinitely delay a decision on the proposed project.
