"WASHINGTON - Thousands of protesters, including a Nobel laureate and a movie star, gathered near the White House on Sunday in opposition to TransCanada's Keystone XL pipeline.
The demonstration is the latest in a series of White House protests aimed at convincing U.S. President Barack Obama to block the $7 billion project that would carry Alberta oilsands crude through six American states to Gulf Coast refineries.
Mark Ruffalo, nominated for an Academy Award last year, and Jody Williams, winner of the 1997 Nobel Peace Prize for her work on banning landmines, were among the celebrities who intended to join hands and encircle the White House despite the fact that Obama was golfing in northern Virginia on a stunning autumn afternoon."
