Rex Tillerson is Secretary of State not Secretary of the Interior. The State Department needs to filter the requests of Tillerson for insider information about the petroleum industry, that includes Governors.
If Trump decertifies the agreement with Iran it will be impossible for Secretary Tillerson to go forward with direct talks with North Korea and will be ostracized by allies in the future.
The Republican Party needs to be people that actually work for the American people and not the Koch Brothers.
If Secretary Tillerson secludes himself to a helpful and supportive staff, I am not surprised.
