On Monday, more protesters gathered outside of the White House as part of a 15-day-long effort to halt the Keystone XL Tar Sands Pipeline, which would cut through the middle of America, from the border with Canada all the way down to the Gulf of Mexico. Protesters spoke out against the pipeline, which has the potential to generate disastrous effects across large regions of the country, pleading with President Obama to not allow the plans for the pipeline to go through.

"We’re asking President Obama to make the right decision, because he can decide yes or no," said Mike Tidwell, the founder and director of the Chesapeake Climate Action Network, in this video from The Nation and On The Earth Productions. "He doesn’t need Congress’s involvement." Watch a video here from Saturday’s protests.
