MONTPELIER, Vt. — Vermont's two U.S. senators are sharply criticizing an environmental impact statement from the U.S. State Department that appears to support construction of the hotly debated Keystone oil pipeline from Canada to Texas.

Both Sens. Patrick Leahy and Bernie Sanders say the pipeline would enable a big increase in oil production and add to greenhouse gas emissions blamed for climate change.

Leahy is labeling the project misguided and an environmental travesty.

Sanders says the State Department appears to be ignoring the problem of climate change.

The State Department issued its environmental impact statement for the project on Friday, saying it had no major objections to the Keystone pipeline.
