Objectives: In this note, we argue that resistance to mask mandates emerged out of successful efforts to recruit sheriffs into right-wing extremism (RWE) and its foundations in white supremacy, nativism, and anti-government extremism. Methods: We draw on upon historical analysis and a national survey of sheriffs. Results: We show how RWE movements recruited sheriffs and that a substantial share of sheriffs adopted RWE attitudes. We argue that this radicalization of county sheriffs primes them to resist a core component of federalism: mandates by supra governments. We identify a relationship between sheriffs. RWE attitudes and their resistance to enforcing COVID-19 mask mandates. Conclusion: Our work demonstrates the importance of considering the implications of violent extremism in the United States, particularly as it aligns with local law enforcement. ¿ 2023 The Authors.
