In June 2013, she left her post as Assistant Secretary and returned to academia. Assistant Secretary of State (A/S) is a title used for many executive positions in the United States Department of State, ranking below the Under Secretaries.  A set of six Assistant Secretaries reporting to the Under Secretary for Political Affairs manage diplomatic missions within their designated geographic regions, plus one Assistant Secretary dealing with international organizations.  Assistant Secretaries usually manage individual bureaus of the Department of State.  When the manager of a bureau or another agency holds a title other than Assistant Secretary, such as "Director," it can be said to be of "Assistant Secretary equivalent rank."  Assistant Secretaries typically have a set of deputies, referred to as Deputy Assistant Secretaries (DAS). The Asia Group LLC (TAG) is a strategy and capital advisory group based in Washington DC with an affiliated office in Hong Kong.

He was elected in November 2004, defeating the incumbent president, Geri Small.  However, after a conflict with reservation vice president Rick Wolfname that began in July 2007 escalated, the Northern Cheyenne tribal council declared that it would oust Little Coyote as the tribe's president.  Little Coyote was forcibly removed from office and arrested for trespassing in the tribal office building on December 28, 2007.  It is worth noting that the move by the tribal council to remove Little Coyote from office was deemed unconstitutional and void by the Northern Cheyenne Constitutional Court.  The Constitutional Court was however overruled by Bureau of Indian Affairs' regional director Ed Parisian, and later the Assistant Secretary of Indian Affairs Carl J. Artman.  Their involvement in this matter set a historical precedence of the BIA directly meddling with tribal governments.
