Tenure: 114th–119th Congresses
Years of Service: 2015–Present
Rep. Mark DeSaulnier has established a strong and consistent record in support of animal protection during his time in Congress. Although animal welfare is not the primary issue for which he is known, he has repeatedly supported legislation and policies that protect wildlife, strengthen farm-animal welfare standards, promote humane treatment, and preserve environmental safeguards that benefit animals. His record combines favorable votes on major animal protection priorities with affirmative support for important legislation, making him one of the more reliable allies in California’s congressional delegation.
One of the clearest examples of DeSaulnier’s commitment to animal protection is his cosponsorship of the SAFE Act (Safeguard American Food Exports Act), legislation that would permanently prohibit the slaughter of American horses for human consumption and ban the export of horses for slaughter abroad. The SAFE Act remains one of the most important federal horse protection measures before Congress and has long been a cornerstone priority for efforts to end the horse slaughter pipeline.
DeSaulnier’s broader record reflects a strong commitment to conservation and wildlife protection. He has consistently supported environmental safeguards and measures designed to preserve biodiversity and protect vulnerable species. Throughout his congressional career, he has opposed efforts to weaken federal wildlife protections and has maintained one of the strongest environmental voting records in Congress. This conservation ethic has translated into a consistently favorable record on animal protection issues.
His voting record on recent benchmark animal protection measures has been particularly strong. DeSaulnier 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. Because lead poisoning remains a significant threat to condors, eagles, loons, swans, and other wildlife species, the vote reflected support for maintaining important tools to reduce wildlife mortality.
DeSaulnier also voted against the Greene Amendment, which sought to prohibit federal support for cultivated meat and related technologies. Cultivated meat has the potential to reduce reliance on conventional animal agriculture and dramatically decrease the number of animals raised and slaughtered for food. By opposing the amendment, DeSaulnier supported continued innovation in technologies that could reduce animal suffering within the food system.
On farm-animal welfare, DeSaulnier voted against the Farm, Food, and National Security Act, which included the Save Our Bacon Act, preempting state farm-animal welfare laws such as California’s Proposition 12 and Massachusetts’ Question 3. That vote helped defend one of the most consequential animal welfare laws enacted anywhere in the country and preserved states’ ability to establish stronger standards for the treatment of farm animals. DeSaulnier also signed on to a critical letter opposing the Save Our Bacon Act.
While DeSaulnier has not built a legislative portfolio as extensive as some of Congress’s most visible animal protection leaders, his combination of affirmative support for horse protection legislation and consistently favorable votes across wildlife, farm-animal, and food-system issues demonstrates a sustained commitment to humane policies. Unlike many members whose records rely primarily on environmental issues, DeSaulnier’s support extends into core animal protection priorities as well.
Taken as a whole, DeSaulnier’s record places him in the Champion of Animal Protection category. His support for the SAFE Act, opposition to efforts to weaken wildlife protections, support for alternatives that could reduce animal suffering, and defense of state farm-animal welfare laws demonstrate a broad and consistent commitment to animal protection.

115th Congress
✅ Cosponsor of the Dog and Cat Meat Trade Prohibition Act, H.R. 1406, bipartisan legislation to prohibit the slaughter of dogs and cats for human consumption and ban the sale, transport, possession, and trade of dogs, cats, and their parts for that purpose. The bill established federal criminal penalties to ensure the United States maintains a clear prohibition on the dog and cat meat trade.
✅ Cosponsor of the Humane Cosmetics Act, H.R. 2790, bipartisan legislation to phase out animal testing for cosmetics and prohibit the sale of cosmetics developed or manufactured using new animal testing.

✅ Voted “Nay” on H.J. Res. 69, a Congressional Review Act resolution (House Roll Call Vote 98) to overturn an Obama administration rule protecting wildlife on National Wildlife Refuges in Alaska. The rule prohibited inhumane predator-control practices, including killing bear cubs and wolf pups in their dens, baiting bears with food to shoot them at close range, and aerial shooting of wolves and other predators. The resolution passed Congress and was signed into law, eliminating these federal wildlife protections. A “Nay” vote is the pro-animal position because it sought to preserve safeguards against some of the cruelest and most unsporting predator-killing practices on federal refuge lands.
✅ Voted “Aye” on the Roskam–Blumenauer Amendment (House Roll Call Vote 202), to H.R. 2, the Agriculture and Nutrition Act of 2018, to strengthen the federal animal fighting law by clarifying that its prohibitions apply throughout all U.S. territories. The amendment closed a legal loophole that had allowed organized dogfighting and cockfighting to continue in certain U.S. territories despite being illegal elsewhere in the United States. An “Aye” vote is the pro-animal position because it strengthened federal protections against organized animal fighting.
