The Keystone pipeline system, an addition to which has been the subject of environmental protests for years, leaked about 383,000 gallons of crude oil in North Dakota, covering an estimated half-acre of wetland, state environmental regulators said.

The spill, which has been contained, occurred in a low-gradient drainage area near the small town of Edinburg in northeast North Dakota, less than 50 miles from the Canadian border, according to Karl Rockeman, the director of the state Department of Environmental Quality’s division of water quality.
It looks like the Keystone Pipeline has leaked out a lot of oil in North Dakota. The Keystone Pipeline was delayed due to the Obama administration but was greenlit when Trump came into office.

With the enviorment being a major issue this election this leak doesn't bode well for Trump.
