Montana residents and Hollywood stars will lead the protests at Day 4 of the Tar Sands Action at the White House. The proposed Keystone XL pipeline, which 162 Americans have been arrested protesting this week, would run through Montana and six other states. Among those planning on being arrested today are film star Margot Kidder, who played Lois Lane in four Superman movies, and actress Tantoo Cardinal, an iconic Cree actress who appeared in Dances with Wolves, Legends of the Fall, Smoke Signals and more. Cardinal, who was born in Ft. McMurray, Alberta, the capitol of the tar sands, was made a Member of the Order of Canada in 2009. Cardinal will risk arrest to stop the destruction of her homeland and push President Obama to help shut down the tar sands by denying a permit for the Keystone XL.
