The letter from Claude A. Cox, Principal Chief of the Creek Nation, expresses concerns over the delay in the publication of final rules and regulations for the implementation of the Food Stamp Act of 1977. He requests immediate action on the issuance of regulations for the Commodity program and urges no further delays, as it is crucial for serving eligible Indian families. Cox also asks for interim rules and regulations for the Food Stamp Program to be published once legal and policy questions are resolved. Cox emphasizes the importance of these programs for the health and nutrition of Indian families.
