NORTH DAKOTA (KSAZ)
The Dakota Access Oil Pipeline is something that has been argued over for years but just recently the clash between protestors and the builders turned violent.
On Saturday demonstrators supporting the Standing Rock Sioux Tribe faced off with the private security officers from Dallas-based Energy Transfer Partners who are building the pipeline.
Protestors say they worry that the massive pipeline, which is slated to run through four states, could upset the reservation's sacred sites and taint the land's drinking water.
Once the U.S. Army Corps of Engineers granted the permit to build the pipeline, several hundred protestors forced construction to halt. Now it is up to a judge to make the final decision.
A federal judge will rule before September 9 whether construction can be halted on the pipeline.
