This bill aims to expand acceptable forms of identification for firearm purchases, specifically allowing members of federally recognized Tribes to use their Tribal government identification documents. It amends section 922(t)(1)(D) of title 18, United States Code, to explicitly include these documents as valid identification when obtaining a firearm from a federally licensed firearms dealer . This change is designed to ensure that Tribal members have a recognized form of identification for these transactions, aligning with federal recognition of their governments. The legislation further adds a new definition to section 921(a) of title 18, United States Code, clarifying what constitutes a "Tribal government" by referencing the official list published under the Federally Recognized Indian Tribe List Act of 1994. These amendments are intended to streamline the process for Tribal members to exercise their right to purchase firearms, recognizing the validity of their government-issued identification. The provisions of this Act will become effective 90 days after its enactment.
