According to a report by the Associated Press, Koch officials have vowed to spend between $300 million and $400 million to shape the 2018 midterm elections.

The conservative Koch brothers’ network declared Monday that it will not help elect the Republican Senate candidate in North Dakota, turning its back on the GOP in a marquee election — at least for now.

Charles and David Koch are majority owners of Koch Industries, a multinational corporation with headquarters in Wichita. The company employs over 120,000 in 60 countries, according to the Koch Industries web site.
