An investigation into the conduct of Interior Secretary Ryan Zinke is escalating. According to recent reports, the department’s inspector general has sent one of its several probes upstream, to the U.S. Department of Justice. That’s bad news for Zinke—investigations are typically referred to the DOJ only after evidence of criminal activity has been found. A spokesperson for the inspector general’s office did not reveal the Zinke allegation in question, but there sure are a lot to choose from: a suspect real estate deal with oil giant Halliburton; taxpayer-funded trips with his wife; or, perhaps, the one involving redrawing national monument boundaries to benefit a state lawmaker. I guess we'll find out soon.
