An es­tim­ated 12,000 pro­test­ers circled the White House on Sunday, protest­ing the pro­posed Key­ston XL pipeline that would bring car­bon-heavy tar-sands oil from Canada to U.S. re­finer­ies on the Gulf Coast. The pro­test­ers gathered on a pleas­ant, sunny af­ter­noon. Many were heard chant­ing, “Stop the pipeline; yes we can.” Here’s a look at the scene from the protest near the North Lawn of the White House.
