Added a new definition for 'Tribal government' meaning the recognized governing body of any Indian or Alaska Native Tribe as listed under the Federally Recognized Indian Tribe List Act of 1994. This is distinct from the existing 'Tribal organization' definition.

Expanded the Foundation's best practices outreach obligation from 'Indian Tribes' to 'Indian Tribes and Tribal governments.'

Narrowed the list of entities eligible to receive Foundation funds under Section 118(a)(2) by removing 'United States and international nongovernmental organizations' and 'foreign government entities,' while retaining regional organizations, Indian Tribes, and Tribal organizations.
