Tenure: 118th–119th Congresses
Years of Service: 2023–Present
Rep. Kevin Mullin has quickly built one of the stronger animal protection records among California’s newer members of Congress. Although he is still early in his House tenure, Mullin has already combined a consistently favorable voting record with affirmative support for major animal protection legislation involving horse slaughter, animal fighting, animal testing reform, plant-based nutrition, wildlife protection, and farm-animal welfare.
Mullin’s legislative record includes cosponsorship of the SAFE Act, legislation that would permanently prohibit the slaughter of American horses for human consumption and ban the export of horses for slaughter abroad. He has also cosponsored the FIGHT Act, which would strengthen federal enforcement against animal fighting operations and associated criminal activity. In addition, he has supported the FDA Modernization Act 3.0, legislation designed to advance alternatives to animal testing, and the ADD SOY Act, which would expand access to plant-based milk options in school meals.
His wildlife record has also been strong. Mullin voted against H.R. 845, the Pet and Livestock Protection Act, which would remove federal Endangered Species Act protections for gray wolves. He also voted against H.R. 556, the Protecting Access for Hunters and Anglers Act, preserving federal authority to regulate lead ammunition and lead fishing tackle on federal lands and waters. Lead poisoning remains a serious threat to condors, eagles, loons, swans, and other wildlife species, making this vote an important marker of support for wildlife protection.
Mullin also voted against the Moore Amendment, which sought to preserve commercial greyhound racing operations in West Virginia by creating an exemption from broader federal restrictions. His vote aligned with efforts to end commercial greyhound racing and prevent a state-specific carveout for an industry built around animal exploitation.
On farm-animal welfare, Mullin signed the congressional letter opposing the EATS/Save Our Bacon Act, one of the most dangerous federal preemption proposals aimed at state animal welfare laws. The EATS/Save our Bacon Act would undermine measures such as California’s Proposition 12 and Massachusetts’ Question 3, both of which establish baseline standards for the treatment of farm animals whose products are sold within those states. Mullin later voted against the Farm, Food, and National Security Act, which included similar preemption language threatening those state laws.
Mullin also voted against the Greene Amendment, which sought to prohibit federal support for cultivated meat and related technologies. By opposing the amendment, he supported continued research and innovation in alternatives that could reduce reliance on conventional animal agriculture and decrease the number of animals raised and slaughtered for food.
What distinguishes Mullin is the breadth of his early record. He has not simply cast favorable votes when animal issues reached the House floor; he has cosponsored priority bills, signed public letters, and taken consistent positions across several major issue areas. His record spans horses, animal fighting, animal testing, plant-based food access, wolves, lead poisoning, greyhound racing, farm-animal welfare, and cultivated meat innovation.
Taken as a whole, Mullin’s record places him firmly in the Champion of Animal Protection category. His early tenure has already produced a strong and varied portfolio of animal protection work, and he has established himself as one of the most reliable pro-animal votes in California’s congressional delegation.
