A federal judge has heard testimony in the Standing Rock Sioux Tribe's request to temporarily block the construction of a four-state oil pipeline near their reservation, which straddles the North Dakota-South Dakota border. Here are some things to know about the pipeline and the tribe's ongoing protest:What is the Dakota Access pipeline? Dallas-based Energy Transfer Partners' Dakota Access Pipeline is a $3.8 billion, 1,172-mile project that would carry nearly a half-million barrels of crude oil daily from North Dakota's oil fields through South Dakota and Iowa to an existing pipeline in Patoka, Illinois, where shippers can access Midwest and Gulf Coast markets. Mostly members of the Standing Rock Sioux tribe, but they've been joined by other American Indians, First Nations from Canada, and non-Native Americans from across the country. Yes, but nothing like in North Dakota.
