PORTLAND, Maine - Environmental activists in Maine and across the country mobilized for a so-called "day of action" today to oppose to the controversial Keystone XL Pipeline.
Protestors gathered late Tuesday afternoon in Congress Square Park in downtown Portland.
Glen Brand is with the Sierra Club Maine, one of the groups sponsoring the rally. He says activists want President Obama to keep his promise to reject the pipeline.
"Tar sands is the dirtiest form of oil on earth," Brand says, "and it poses a threat to our climate by dramatically increasing the amount of carbon pollution which causes all the climate disruption problems that we are experiencing."
The day of action comes as Republicans in the GOP-controlled U.S. Senate seek to win approval for construction of the long-delayed pipeline, which would transport crude oil from Alberta, Canada, to the mid-western United States.
