North Dakota pipeline fight gives spark to Native American activism

A Native American tribe's efforts to halt construction of a crude oil pipeline in North Dakota have swelled into a movement, drawing international attention and the support of movie stars and social media, and making a major oil company blink.

While the tribe's lawyers work to persuade a federal judge to withdraw permits for the pipeline in a ruling expected on Friday, thousands of protesters gathered at campgrounds near Standing Rock Sioux Tribe lands.
