Minority Leader Nancy Pelosi voiced her opposition Thursday to a House Republicans bill approving the Keystone XL pipeline because it would exempt TransCanada from having to pay into the Oil Spill Liability Trust Fund. “If you were 100 percent for the Keystone pipeline, you would have to have a problem with the legistlation on the floor,” Pelosi said at her weekly news conference. “Should there be a leak, TransCanada will be exempted from paying into the Oil Spill Liability Trust Fund, even though the tar sands component of what they’re transmitting is highly corrosive.”
