In North Dakota, the company building the Dakota Access pipeline says it is preparing to drill beneath Lake Oahe on the Missouri River within two weeks, even though the U.S. Army Corps of Engineers has not granted a permit. The announcement shocked and infuriated opponents of the $3.8 billion pipeline, which has faced months of resistance from the Standing Rock Sioux Tribe along with representatives of over 200 other indigenous tribes and non-Native allies. Opponents, who call themselves "water protectors," say they were promised by an Army Corps of Engineers official that the Dakota Access pipeline would be delayed by at least 30 days, should the Obama administration agree to a permit. But pipeline builder Energy Transfer Partners said Tuesday the Army Corps was mistaken when it said the company had agreed to slow construction. The announcement came one week after President Obama said the Army Corps was looking at a possible "reroute" of the pipeline.
