Congressman Raúl Grijalva and Secretary of the Interior, Ryan Zinke, recently locked horns in a bitter and very public war of accusations. Grijalva called on Zinke to resign in light of several ethics investigations and Zinke in turn took to Twitter to personally attack the Arizona Congressman. Grijalva is set to take over the chairmanship of the House Committee on Natural Resources, the committee that oversees Zinke’s Department and makes critical decisions about public lands, energy and the environment. And it turns out Raúl Grijalva's plans for the committee are quite different from his Republican predecessor.
