This bill proposes to allow members of federally recognized Tribes to use their official Tribal government identification documents when acquiring firearms from federally licensed dealers. It achieves this by amending federal law, specifically section 922(t)(1)(D) of title 18, United States Code, to explicitly include "a valid identification document issued by a Tribal government" as an acceptable form of identification for such transactions. The legislation also establishes a clear definition for the term "Tribal government," linking it to the list of federally recognized Tribes published under the Federally Recognized Indian Tribe List Act of 1994. This ensures consistency and proper identification of eligible Tribal entities. The amendments made by this Act are set to become effective 90 days after its date of enactment, facilitating a standardized process for firearm purchases by Tribal members.
