A historic gathering is taking place against the Dakota Access pipeline at Standing Rock. Thousands of people, and around 300 Native nations, have gathered to stop Big Oil’s pipeline, which threatens sacred Native grounds and the environment. To give an eyewitness account of this growing movement, as well as essential historical context, Abby Martin interviews legendary Native leader Dennis Banks. Banks is a founder of of the American Indian Movement (AIM), a leader in the 1973 Wounded Knee standoff and many other actions over five decades.
