Watch activist and actor Mark Ruffalo on the front lines of #StandingRock with protectors as a few miles away hundreds of law enforcement personnel are mobilizing, preparing for a possible raid of the new winter camp just east of the Sacred Ground site. Law enforcement today warned protectors camping at the new site to vacate, or all will be arrested. Ruffalo spoke from the Prairie Knights Casino just south of the new winter camp yesterday. Here is a Ruffalo sharing his message of solidarity to the community of Standing Rock. The panel discussion included with Dallas Goldtooth, Kandi Mossett, Chase IronEyes, Bobby Jean Three Legs of the International Indigenous Youth Council, and Krystal Rain Twobulls.
