"This Charter establishes the Tribal Nations Leadership Council (TNLC). [...] The TNLC will serve to facilitate dialog and coordinate efforts between the Department of Justice and tribal governments, furthering the government-to-government relationship between the United States and tribal nations. Primarily, the TNLC is expected to provide perspective on the Department's activities in Indian Country and raise issues that have tribal implications. Possible areas of discussion include, but are not limited to, law enforcement, civil rights, tax issues, environmental concerns and issues regarding sacred sites."
