Clarkson, a member of the Choctaw Nation of Oklahoma, is a former law professor who has taught at the University of Michigan and New Mexico State, and been involved in several businesses. He referred questions to a department spokeswoman, who did not respond to questions sent by email.
The story begins with what sounds like an improbable idea: In 2008, the Lower Brule Sioux tribe in South Dakota decided to buy a nearly insolvent Wall Street financial services company. The tribe, which was receiving federal aid to reduce poverty, according to a report by Human Rights Watch, turned to Clarkson to obtain a loan, and a loan guarantee from the Interior Department. (The guarantees are intended to encourage banks and other entities to lend to Indian businesses that might not otherwise find funding. The government agrees to reimburse any covered debt that the borrower fails to pay off.)
