(CNN) - Republicans called on President Barack Obama to make a decision on the controversial Keystone XL pipeline in their weekly address Saturday, saying the delay was a result of political calculations.
Speaking for his party, Wyoming Sen. John Barrasso said the project has received wide support, except from Obama's political base.
"Everyone from members of the United States Chamber of Commerce to members of labor unions support this project," Barrasso said. "But the President has threatened to veto this bill because the pipeline is opposed by a number of extreme environmental groups. These are the same groups who in the past have supported the President and he needs their support for his reelection.
Barrasso asserted it was "time for the President to stop playing politics."
Opposition to the Keystone XL pipeline, which would transmit oil from Canadian tar sands in Alberta to refineries on America's Gulf Coast, has come under fire from environmental groups who say the project would impact communities along the route and promote the use of non-renewable energy.
The Senate is expected to vote Saturday on a provision to speed up a decision on the pipeline as part of a larger proposal to extend the payroll tax cut by two months.
