His public record includes votes and statements aimed at rolling back environmental regulations and challenging climate-focused initiatives.
Opposes most new federal gun restrictions and advocates nationwide permitless (constitutional) carry and expanded gun rights, including lowering federal age limits for handgun purchases and repealing federal gun-free-school-zone restrictions.
