Premise: Kevin "Jack" Haugrud was the acting United States Secretary of the Interior, serving since the end of the Obama administration on January 20, 2017 until the swearing in of Ryan Zinke on March 1, 2017. Until becoming Acting Secretary, Haugrud was deputy solicitor of the Department of the Interior.
Hypothesis: Ryan Zinke served as acting United States Secretary of the Interior longer than Haugrud did.
