"Trump told his aides that he is afraid Zinke has broken rules while serving as the interior secretary and is concerned about the Justice Department referral." He remains a key member of Trump's Cabinet, though.

Trump Administration: Corruption is a Feature
This week, Interior’s Office of Inspector General referred the inquiry — one of several probes into the secretary’s conduct — to the Justice Department to determine whether a criminal investigation is warranted. That referral concerns Zinke’s involvement in a Whitefish, Mont., land development deal backed by David J. Lesar, chairman of the oil services firm Halliburton.
“I want you to know that whatever assistance you need to protect and promote your vision for the park, please let me know and I will make sure that it’s communicated and executed,” Malmquist wrote in an exchange that Zinke forwarded to his assistant.
The Zinkes own two companies, Continental Divide International and Double Tap, that have several parcels of land near the proposed project. According to Zinke’s most recent financial disclosure form, he received between $15,001 and $50,000 in rent or royalties from Continental Divide International last year and between $5,001 and $15,000 from Double Tap.
