Sen. John Ensign (R-NV) who has been named Humane Legislator of the Year by the Humane Society of the United States for legislation he authored to help crack down on animal fighting and to stop the slaughter of American horses for consumption.
HSUS also noted:
"Sen. Ensign didn't stop with those two bills. He also co-sponsored the Pet Animal Welfare Statute, S. 1139, which will require commercial breeders who sell directly to the public to follow the basic care standards outlined in the Animal Welfare Act. What's more, he co-sponsored the Captive Primate Safety Act, S. 1509, which would prohibit the interstate and foreign commerce in nonhuman primates (chimpanzees, monkeys, lemurs, and others) for the pet trade. The senator also supported millions of dollars in increased funding for the enforcement of existing animal welfare laws."
Other House and Senate members from both parties were also recognized as Humane Champion Award winners, Legislative Leader Award winners and Humane Advocate Award Winners.
