Indian Trust Asset Reform Act

Indian Trust Asset Reform Act Reaffirms the federal government's fiduciary responsibilities to Indians. Indian Trust Asset Management Demonstration Project Act of 2015 Directs the Department of the Interior to establish a 10 year (but may be extended at Interior's discretion) Indian trust asset management demonstration project that allows Indian tribes to propose Indian trust asset management plans. Authorizes Interior to establish an Under Secretary for Indian Affairs who is to: (1) report directly to the Secretary of the Interior; (2) assume the functions of the Assistant Secretary for Indian Affairs; and (3) coordinate with the Special Trustee for American Indians to ensure an orderly transition of the functions of the Special Trustee to the Bureau of Indian Affairs, or to any other agency or bureau within Interior. Requires Interior to prepare a transition plan and timetable for the termination of the Office of Special Trustee for American Indians.
